# Mathematical Expressions used in Math Word Problems

To solve any mathematical problem, it is important to understand and know the mathematical meaning of the words used in the problem. Many mathematical expressions or even general expressions have the same meaning and may indicate a relationship between quantities or a mathematical operation (such as addition, subtraction, multiplication, and division).

Equality Expressions

All of the following expressions represents that two quantities are equal (=).

• is equal to (or equals)
• is the same as
• the result is
• yields
• gives

For example, 2+5 is equal to 7.

Note: The word “is” is also used to mean “equals”. For example, 8 is 5 more than 3, or 8 equal 5 + 3.

All of the following expression shows that the number $X$ and $Y$ are added

Subtraction Expressions

All of the following expressions show that the number $Y$ is to be subtracted from the number $X$

Multiplication Expressions

The following expression can be used if the numbers $X$ and $Y$ need to be multiplied.

For multiplication of two or more numbers symbol $\times$ or $\cdot$ is used. In algebra, a number before a variable is a coefficient, such as $4Y$ means 4 times $Y$, where 4 is coefficient.

Division Expressions

All of the following expression indicate the division of the numbers $X$ and $Y$ (in the order $X \div Y$.
