Question

{30-[12-(3+4)+2]×2}-15 how do I get my answer

Answer 1

So with this equation, you have to work inside out with the parentheses. Firstly, solve 3+4:
`\{30-[12-7+2]*2\}-15`

Next, solve 12 - 7 + 2:
`\{30-7*2\}-15`

Next, solve 7 x 2, then 30 - that product:
`16-15`

Lastly, solve 16 - 15, and your answer will be 1.
