4+2(7)= 62+8×3= 3(2+5)−5(3)+8= 24−6+12÷2×3=

4 + 2(7) = 18 62 + 8 × 3 = 86 3(2 + 5) − 5(3) + 8 = 14 24 − 6 + 12 ÷ 2 × 3 = 36

1. 4 + 2(7) First, we need to perform the multiplication before addition due to the order of operations (PEMDAS/BODMAS). So, 2 multiplied by 7 equals 14. Then we add 4 to get the final result. 4 + 2(7) = 4 + 14 4 + 14 = 18

2. 62 + 8 × 3 Again, perform the multiplication first and then addition. 8 times 3 equals 24. Then add 62. 62 + 8 × 3 = 62 + 24 62 + 24 = 86

3. 3(2 + 5) − 5(3) + 8 Here we have parentheses, multiplication, addition, and subtraction. We start with the arithmetic inside the parentheses. 2 + 5 equals 7, and 3 multiplied by 7 equals 21. 5 times 3 equals 15. Now we combine these with the remaining numbers using addition and subtraction. 21 - 15 + 8 First, subtract 15 from 21, which equals 6, and then add 8. 6 + 8 = 14

4. 24 − 6 + 12 ÷ 2 × 3 Order of operations tells us to handle division and multiplication before we do addition and subtraction. 12 divided by 2 equals 6, and 6 times 3 equals 18. Now we perform the addition and subtraction. 24 − 6 + 18 Start with the subtraction: 24 minus 6 equals 18, and then add the other 18. 18 + 18 = 36
