Question

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

Answer 1

Answer:

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

Step-by-step 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
