Question

The difference between the product of (-15) and (-2) and the sum of (-10) and (+3)

Write a mathematical expression that represent the statement given above.

​

Answer 1

Answer: 30 - (-7)

Explanation:

I like to use brackets and put all the pieces together one at a time to ensure I'm doing exactly as the question asks:

1. difference ([product of (-15) and (-2)] and [sum of (-10) and (+3)])
2. difference [ (-15 × -2) and (-10 + 3)]
3. (-15 × -2) - (-10 + 3)
4. 30 - (-7)

Remember:

difference means subtraction

product means multiplication

sum means addition

Answer 2

(-15)(-2) - (-10)+3 (or in other words 30-(-7))

Step-by-step explanation:

Product means to multiply

Sum means to add
