Translating Mathematical Phrases to Numerical Expression

A numerical expression is a mathematical sentence involving only numbers and one or more operation symbols.

Let us translate the given Mathematical phrases above to their numerical expressions.

1. The sum of seven and eleven

7 + 11

"Sum of" tells us that we need to add them.

2. Three subtracted from fifteen

15 - 3

"Subtracted from" obviously means that we need to subtract 3 from 15.

3. Seven times eight

7 × 8

"Times" means that we need to multiply them.

4. The quotient of twenty and two

20 ÷ 2

"Quotient of" means we need to divide as we call the answer in division as quotient.

5. Fifteen less than four times seven

(4 × 7) - 15

We need to multiply 4 and 7 first. Then, "less than" means that we need to subtract 15 from the their product.
