1. Equals
   Approximately equal
2. Equal by definition
   Calculate this expression first

Although we see this symbol in nearly every math equation, some people might have a difficult time identifying it. However, when you read the expression or equation out loud, you will definitely hear the name of the symbol.

1. Add
   Multiply
2. Subtract
   Divide

The subtraction sign might be a very easily recognizable mathematical symbol. It is one of the first symbols we are taught in elementary math, and it's as simple as a single horizontal line.

1. Strict inequality
   Not equal sign
2. Plus sign
   Parentheses

If two variables are not equal to each other, you will probably see this symbol between them. Although this symbol is used mainly in more advanced math and theory, it is sometimes seen in algebra.

1. Less than
   Equal to
2. Greater than
   Multiply

While many coders out there might see this as the beginning of a command, in math, it means something completely different. This little caret tells us the relationship between two numbers or variables.

1. Addition symbol
   Modulo
2. Exponent
   Division symbol

Just like multiplication, there are several symbols for division. These include the symbol you see here with a single horizontal line that has a dot above and below it and a back slash that separates two numbers.

1. Greater than or equal to
   Both plus and minus
2. Plus sign
   Division

The plus sign might be one of the most recognizable mathematical symbols around. It is just a cross section of two lines. It seemingly shows that two things are brought together, much like being added to each other.

1. Asteroid
   Astersign
2. Square root
   Asterisk

While the asterisk in most writing points to something that you should pay attention to, the asterisk in math is to show multiplication. There are several signs for multiplication, and this is one of them.

1. Caret
   Power dot
2. Cube root
   Degree

Carets are used to represent exponents. In this case, a^b means "a to the b power," so if a = 3 and b = 2, the equation would be 3^2=9. Symbols like this were used to show work when it wasn't possible to make subscript.

1. Infinite line
   Line segment
2. Parallel line
   Congruent line

The line above A and B stops, it doesn't have arrows that tell you if it continues in one direction or both. This means that you are looking at a line segment that begins at A and ends at B.

1. Obtuse angle
   Arc
2. Right angle
   Perpendicular line

There are several symbols for angles, but this one shows that the angle is a right angle. All right angles are 90 degrees. This symbol can help you determine a lot of the measurements within a triangle that you're looking at.

1. Spherical angle
   Similarity
2. Triangle
   Degree

Although you may be used to seeing the degree symbol on things that measure temperature, in math, it used to help measure angles. It's often seen in geometry and advanced analytic geometry.

1. Arc
   Distance
2. Pi
   Radians

When you see the arc symbol above two letters, the number that it is equal to is generally found in degrees. The two letters are considered points on a circle, and every two points on a circle create an arch.

1. Perpendicular
   Parallel
2. Pi
   Double prime

It makes sense that the symbol for parallel would be two parallel lines, but those lines do have to be vertical. If they were horizontal, you would get the equal sign, and that could get confusing.

1. Greater than
   Subtraction
2. Division
   Less than

There are several symbols in mathematics that show us the relationship between two numbers or variables. If you're ever mixed up by the greater than or less than symbol, draw teeth on the open end, and remember that the alligator always likes to eat the biggest number.

1. Degree
   Angle
2. A measured angle
   A right angle

A simple angle symbol tells the mathematician that the angle in this situation has not been solved or measured. If this symbol had an arch connecting the two lines, it would be considered a measured angle.

1. Theta
   Kappa
2. Pi
   Omega

There are several constants in math. These are symbols that have a specific value given to them. Pi is the symbol for ratio of a circle's circumference as compared to its diameter. It equals approximately 3.14.

1. Side 8
   Theta
2. Grad
   Lemniscate

While there is no specific number assigned to the infinity symbol, it is a great way to give infinity a value that allows you to create equations and expressions without having to guess a number.

1. Floor brackets
   Down brackets
2. Small brackets
   Half brackets

When you see floor brackets in an equation, you should always round that number to the lower integer. For example, if you see floor brackets around 5.8, you should round this number down to 5.

1. Sigma
   Absolute value
2. e constant
   Set

When you see something like this: | 6 |, you should always take the absolute value of the number within the equation. The absolute value of a number could be different than the number you see. For example, the absolute value of -7 is 7.

1. Multiply
   Divide
2. Subtract
   Absolute value

For math beginners, a great way to understand multiplication to to think of it as a faster way to add things. For example, 3X3 is the same as 3+3+3, because you are adding three to itself three times.

1. Both multiplication and division
   Both plus and minus
2. Division
   Subtraction

For those of you who have taken advanced algebra, you probably recognize this symbol as a part of the quadratic formula. The symbol is also used to make approximations more precise.

1. Division
   Calculate this expression first
2. Multiplication
   Exponent

In algebra, there are times when using the X for the symbol of multiplication can be a little confusing to those reading equations. In this case, the dot is generally used to show that two numbers or variables need to be multiplied.

1. Square root
   Division slash
2. Times sign
   Percent

Percent symbols are seen throughout various sciences, and are often used in the results of mathematical equations. Percent means for every 100. This symbol is used to reduce the number of characters needed to convey a result.

1. Square root
   Percent
2. Period
   Power

The square root symbol might be the most interesting one used in math. It is almost like a check mark with an extended tail that covers whatever number needs to be rooted. While this action can be difficult for those just starting out in math, it becomes a little easier with practice.

1. Notated angle
   Understated angle
2. Spherical angle
   Unknown angle

Angles are interesting, and they can be found just about anywhere you look. While many people don't think that spheres have angles, when you connect the radius to another radial point, you create an angle with the focus (center) of the circle.

1. Percenting
   Percent
2. Angular percentage
   Per-mille

Percent means parts per one hundred. Therefore, per-mille means parts per thousand. This symbol is often used in a lot of chemistry equations, as the numbers are so small that using a percentage isn't necessarily helpful.

1. The distance between a and b
   The difference between a and b
2. The variables between a and b
   Both a and b are equal

Seeing two variables between long verticle lines is generally showing the distance between then. This helps you get a greater understanding of where these two points land on a grid or chart.

1. Circle
   Triangle
2. Square
   Angle

If you thought this one was a trick question, we understand. While many symbols in math might look difficult, some of them are very transparent. In the case of the triangle symbol, you might see it next to three variables next to each other. This shows that the three variables make the triangle.

1. Approximation
   Addition
2. Equal to
   Degree

While some believe that all math is finite and set in stone, some math is definitely not. There are theoretical aspects to math that have not been completely solved yet, so it's important to incorporate symbols that show this.

1. Parts per mille
   Parts per million
2. Press paper mile
   Punctuate, produce and multiply

While we understand the percent and per mille signs, there are still other mathematical symbols that represent even lower numbers that can be found in a solution. Remember that the higher the "per" is, the smaller the actual value of the number is.

1. Angle
   Vortex
2. Ray
   Wavelength

A ray is a line that starts at one point (or the first variable beneath the ray symbol) and continues on. The starting point of the ray is called the endpoint, but the ray continues on to infinity.

1. Line segment
   Similarity
2. Right angle
   Infinite line

You may be wondering why there are two variables under the infinite line symbol. This is to show you the direction of the line. A straight line only needs two points to give you a direction, even if it is infinite.

1. Not equal to
   Equivalent
2. Multiply then divide
   Divide then multiply

While it looks dangerously close to an equal sign, the sign for an equivalence relationship is usually used in geometry. It shows that two figures are identical to each other without having to show the equation.

1. A disection
   An intersection
2. A subsection
   A union

Intersections are generally used in mathematical theory. When you see a mathematical phrase like this, it translates to everything element that is in A that also belongs in B, but nothing else.

1. United
   Unbroken
2. Union
   Ubiquitous

The best way to describe a union is to think about marriage: what's mine is yours and what's yours is mine. A union in mathematical theory is everything that is in the sets of A and B.

1. Multiplication
   Addition
2. Subtraction
   Division

Much like the look of a fraction, this division symbol tells you that you should divide these numbers to get a number to finish your equation. The symbol actually means the same thing in a fraction, but some choose to keep the fractions as they are.

1. The square root
   The sum
2. The cubed root
   Plus and minus

If you thought the square root symbol was fun, then you would probably love the cubed root. It is rare that someone can find the solution to a cubed root without the help of technology of some sort.

1. Multiply twice
   Double the sum
2. There is no exclamation point.
   Factorial

Factorials can be rather confusing if you don't build a strong math base before you attempt them. It's best to start with positive numbers. So, the factorial for a positive integer is the product of all of the positive integers less than or equal the original integer. Like we said ... it's best to build a strong math base before attempting them!

1. Calculate this expression first.
   Calculate this expression last.
2. Don't calculate this expression.
   This expression is less than zero.

If you ever wondered why you always got those weird meme equations with pictures of fruit wrong, it could be because they have parenthetical expressions in them. Many forget to solve what is in the parentheses first.

1. Cubed
   Squared
2. Doubled
   Divided by 2

When a number is squared, it doesn't necessarily mean to multiply it by 2, it means to multiply it by itself. The only time you would multiply this number by 2 is if the number itself was 2.
