Question

What is the expression for the “sum of 8 times a number and two”?

Answer 1

Let's solve this problem with the number being n.

Since the problem says 8 times a number, and we know that times is multiplication, we are doing 8 * n

Since this is the sum of 8 times a number and 2, we know that we are adding 2 to the product of 8 and a number.

Putting this all together, the answer is 8n + 2.

Answer 2

Hey!

Let's simplify the expression

sum = +
- The term "sum" is used when adding. Therefore, it is equal to "+".

8 times a number and 2 = 8x + 2
- 8 is equal to 8. The term "times" is used when multiplying. Therefore, it is equal to "×". "A number" is a variable. A variable can be any letter. In this case, I have made it "x", which is commonly used.

That gives you: 8x + 2
