-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.
