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.
