Question

How should parentheses be placed in the expression 3 x 8 - 3 +5 ×2 +4 so the expression equals 64

Answer 1

`3*(8-3+5)*2+4=64`

Explanation:

we have

`3*8-3+5*2+4=64`

so

Place the parenthesis in the equation

`3*(8-3+5)*2+4=64`

Verify

Solve first inside the parenthesis

`3*(10)*2+4=64`

Solve the multiplication

`30*2+4=64`

Solve the multiplication

`60+4=64`

Solve the sum

`64=64` -----> is true

therefore

The parentheses were placed correctly
