-63

Explanation:

As PEDMAS states, you do whatever is inside the parentheses first.
In this equation we have #(7+10)# which equals to #17#.
Next step, we have exponents, although there are none so we can skip that step.
Next is division. Currently our equation is #4÷2+3-17*4#. The one division is with #4 ÷2#, which is 2.
Next is multiplication. With #2 + 3 - 17 *4#, you multiply #-17*4#, which gives you #-68#.
Lastly, addition. #2+3-68# is our equation as of right now and if you solve it, it gives you -63.
