Video Solution

Solution Steps

00:09 Remember! Multiply and divide before you add and subtract.
00:22 Add and subtract from left to right, as they're the same in the order.
00:31 Let's rearrange using the commutative property for simplicity.
00:35 Now, solve it step-by-step from left to right again.
00:42 And that's your solution!

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+1821+1= 2+18-21+1=

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

2+18=20 2+18=20

2021=1 20-21=-1

1+1=0 -1+1=0
