Step-by-step solution

According to the rules of the order of arithmetic operations, we begin by enclosing the multiplication exercise inside parentheses:

2(5×3)+4= 2-(5\times3)+4=

We then solve the said exercise inside of the parentheses:

5×3=15 5\times3=15

We obtain the following:

215+4= 2-15+4=

Lastly we solve the exercise from left to right:

215=13 2-15=-13

13+4=9 -13+4=-9
