8+3(5+6)

8+3(11)

8+33

(3)+3(4)^(2)

(3)+(3*16)

(3)+(48)

3+48

51

Answer 12

12 + 7( 9 ÷ 3) + 4

Answer 13

Simplify: 2a – {6b – 4[ a – (b – 3a)]}

Answer 14

12+7((9)/(3))+4

12+7(3)+4

12+21+4

37

Answer 15

2a-[6b-4[a-(b-3a)]]

2a-(6b-4(a-b+3a))

2a-(6b-4(4a-b))

2a-(6b-16a+4b)

2a-(10b-16a)

2a-10b+16a

18a-10b

Answer 16

Answer 17

-51

Answer 18

10. Write as a mathematical expression using parenthesis and brackets. Then evaluate. Subtract 3 from 15. Divide this difference by 2. Multiply this quotient by -2.

Answer 19

\[\frac{15-3}{2}(-2)\]
=-12
