Evaluate.<br><br> 21 ÷ 7 + 20 • 102 • 2 – 3
Novay_Z [31]

To avoid confusion, remember PEMDAS. This is the order of operation.

Parenthesis, Exponents, Multiply, Divide, Add, Subtract

21 ÷ 7 + 20 * 102 * 2 - 3

No parenthesis and no exponents, proceed to multiplication.

20 * 102 * 2 = 4,080

Then, perform division

21÷7 = 3

Then, do addition

3 + 4080 = 4083

Lastly, do subtraction

4,083 - 3 = 4,080

So, 21 ÷ 7 + 20 * 102 * 2 - 3 = 4,080

THEREFORE THE ANSWER IS 4,080
