Question

Evaluate expressions with grouping

Answer 1

The evaluation of the following expressions with groupings are:

• 14
• 14
• 70
• -0.2
• -3
• 77
• 11
• 19

Algebra

8+ (9-3)

= 8 + (6)

= 14

(8+9)-3

= 17 - 3

= 14

14(10 ÷ 2)

= 14 (5)

= 70

(12-3) - (9.2)

= 9 - 9.2

= -0.2

(4-10) + (75 ÷ 25)

= -6 + (3)

= -6 + 3

= -3

80-3

= 77

8+3

= 11

13+ [2(9- 6)]

= 13 + {2(3)}

= 13 + (6)

= 19
