1. (3r + 4.5) - |-d| r=3 d=5

2. (4g - o) ^2 g=5 o=15

3. b^3-y-o b=2 y=6 o=4

4. 3 (-y) - 5b y=10 b=6

5. d + 1/2 (y+g) d=6 y=10 g=8

6. square root of r+bd r=4 b=6 d=5

1. 3 × 3 + 4.5 + 5

= 9 + 4.5 + 5

= 18.5

2. (4 × 5 - 15)²

= 5² = 25.

3. 2³ - 6 - 4

= 8 - 6 - 4

= 8 - (6 + 4)

= 8 - 10 = - 2.

4. 3 × - 10 - 5 × 6

= - 30 - 30 = - 60.

5. 6 + ½(10 + 8)

= 6 + ½ × 18

= 6 + 9 = 15.

6. √4 + 6 × 5)

= 2 + 30 = 32.
