Step 2 : OF
Step 3 : Divide
Step 4 : Multiplication
Step 5 : Addition
Step 6 : Substraction
Calculation:
Evaluate the square root: $\sqrt{}\left(441\right)=21$.
Substitute the value back into the expression: $52\times 3÷4+21÷7\times 3+5-32÷8\times 12$.
Perform the multiplication and division from left to right:
- $52\times 3=156$.
- $156÷4=39$.
- $21÷7=3$.
- $3\times 3=9$.
- $32÷8=4$.
- $4\times 12=48$.
Substitute these values back into the expression: $39+9+5-48$.
Perform the addition and subtraction from left to right:
- $39+9=48$.
- $48+5=53$.
- $53-48=5$.
