Question

Calculate 400- 640 divide by 8 + 70 divide by 5

Answer 1

According to the hierarchy of algebraic operations and applying the associative property, we get that:

`400-640/8+70/5\text{ = 400-(640}/8\text{)+(70}/5\text{)}`

this is equivalent to:

`\text{ 400-(640}/8\text{)+(70}/5\text{)}=400-80+14\text{ =334}`

So that, we can conclude that the correct answer is:

`334`
