So with this equation, you have to work inside out with the parentheses. Firstly, solve 3+4: ![\{30-[12-7+2]*2\}-15](https://tex.z-dn.net/?f=%20%5C%7B30-%5B12-7%2B2%5D%2A2%5C%7D-15%20)
Next, solve 12 - 7 + 2: 
Next, solve 7 x 2, then 30 - that product: 
Lastly, solve 16 - 15, and your answer will be 1.
