Complete the exercise:

4×7×2:4−1×9= 4\times7\times2:4-1\times9=

Step-by-step solution

According to the rules of the order of arithmetic operations, we must first place the multiplication and division exercises within parentheses:

(4×7×2:4)−(1×9)= (4\times7\times2:4)-(1\times9)=

We then proceed to solve the exercise in parentheses from left to right:

4×7=28 4\times7=28

28×2=56 28\times2=56

56:4=14 56:4=14

We obtain the following exercise:

14−9=5 14-9=5
