About This Quiz
Whether you loved or hated math when you were in school, math is a part of our everyday lives. Everyone needs to know how to add, subtract, multiply, and divide to complete basic everyday skills such as calculating tips or measuring ingredients for that fancy cake you want to bake! Some mathematical symbols are easy to identify, plus signs, minus signs, equal signs, and division signs, are some of the most common mathematical symbols you should be able to recognize. However, you may have forgotten some of the other mathematical symbols you learned in school. For example, do you remember what brackets are used for or what an exponent looks like? Do you remember what PEMDAS stands for or how to use parentheses?  Any idea what a spherical angle looks like or an arc? Can you draw the symbol for a parallel line or closed surface integral?
This quiz contains a mix mathematical symbols every math lover or scientist should know. A few of these symbols may seem easy to identify it, but most can stump some of the most qualified mathematicians. Think you can identify all of them? How quickly can you correctly identify them? Find out now by taking this quiz and then challenge your friends!
n/a
Which mathematical symbol is shown here?
Times
It takes at least two factors to make a product. Factors are the numbers that are multiplied and product is the result. The terms “multiplicand†and “multiplier†are also used to show which number is being multiplied (the multiplicand) and how many times (the multiplier).
Measured angle
Brackets
nabla/del
n/a
Which mathematical symbol is shown here?
Less than
The term “less than†is used to refer to quantities (for example, 6 is less than 7). The term “lesser than,†however, is used to refer to quality, meaning one thing is inferior to the other.
Degree
Sigma
Percent
n/a
Which mathematical symbol is shown here?
Greater than
The “greater than†and “less than†signs should really be thought of as a single sign which changes meaning based on its orientation. The sign always opens up to the side that is more and points to the side that is less.

Which mathematical symbol is shown here?
Greater than or equal to
“Less than†and “greater than†are true inequalities in that the two things being compared by them are never equal. While we often refer to “less than or equal to†and “greater than or equal to†as inequalities, they are not, in the strict sense of the word.

Percent
Bakers use the percent as a way to compare the amount of each ingredient to the amount of flour in a recipe. So, a recipe with 50% sugar does not mean sugar makes up half of the amount of ingredients but that the amount of sugar used is half the amount of flour used.

Equals
The equal sign (written as a pair of horizontal lines) was invented by Welsh physician and mathematician Robert Recorde in 1557. Even into the 18th century, a pair of parallel vertical lines was also in use to indicate “equals.â€

Which mathematical symbol is shown here?
Greater than or equal to
Not equal
The term “not equal†indicates that the two amounts being considered are never the same. The terms “greater than†and “less than†are more specific ways to show that the two amounts are not equal. For the possibility that they may be equal at some point, the terms “less than or equal to†and “greater than or equal to†are used.
