Answer 1

Answer:

I will simplify from the inside out: first the parentheses, then the square brackets, being careful to remember that the "minus" sign on the 3 in front of the brackets goes with the 3. Only once the grouping parts are done will I do the division, followed by adding in the 4.

4 – 3[4 –2(6 – 3)] ÷ 2

4 – 3[4 – 2(3)] ÷ 2

4 – 3[4 – 6] ÷ 2

4 – 3[–2] ÷ 2

4 + 6 ÷ 2

4 + 3

7
