3. (2 × 6) + (8 × 4) + 1
4. (8 × 1.95) + (3 × 2.95) + 10.95 × 1.06
5. (12 ÷ 3)² − (18 ÷ 3²) × (4 ÷ 2)

1. 33

2. 60

3. 45

4. 36.057

5. 12

Step-by-step explanation:

Remember that the hierarchy of operations is division, multiplication, addition and subtraction.

1. 3x5+2x8+2=(3x5)+(2x8)+2=15+16+2= 33

2.  First we solve what is inside the parentheses.

1.75 + 2 × 0.25 + 5 × 0.05= 1.75+(2x0.25)+(5x0.05)= 2.5

Then (1.75 + 2 × 0.25 + 5 × 0.05)x24= 60

3. (2 × 6) + (8 × 4) + 1=12+32+1= 45

4. (8 × 1.95) + (3 × 2.95) + 10.95 × 1.06=(8 × 1.95) + (3 × 2.95) + (10.95 × 1.06)=15.6+8.85+11.607= 36.057
