The steps to solving the expression the quantity of the sum of five squared plus three divided by the absolute value of negative 0.5 − 16.4 ÷ 4 are listed below. (PLS HELP ASAP AND DON'T MAKE IT SOUND TO GENIUS...)

Part A: Explain what the missing expression should be for Step 3.

Part B: Explain what the missing expression should be for Step 6.

Step 1 the quantity of the sum of five squared plus three divided by the absolute value of negative 0.5 − 16.4 ÷ 4

Step 2 the quantity of the sum of five squared plus three divided 0.5 − 16.4 ÷ 4

Step 3

Step 4 the quotient of 28 divided by 0.5 − 16.4 ÷ 4

Step 5 56 − 16.4 ÷ 4

Step 6

Step 7 51.9

The first step lists the given expression. In step 2, we show the evaluation of the absolute value function. In step 3, the term with an exponent is evaluated. Step 4 sees the sum in the numerator of the first fraction evaluated, and that fraction is evaluated in step 5. Step 6 sees the second fraction evaluated. Finally, the difference is evaluated in step 7.
