-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.
