Step-by-step solution

According to the rules of the order of arithmetic operations, we must first solve the multiplication exercises.

We place them inside of parentheses in order to avoid confusion during the solution:

2+(3×6)−(3×7)+1= 2+(3\times6)-(3\times7)+1=

We then solve the multiplication exercises:

2+18−21+1= 2+18-21+1=

Lastly we solve the rest of the exercise from left to right:

2+18=20 2+18=20

20−21=−1 20-21=-1

−1+1=0 -1+1=0
