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
Remember that, in lieu of grouping symbols telling you otherwise, the division comes before the addition, which is why this expression simplified, in the end, down to "4 + 3", and not "10 ÷ 2".
