Answer 1

Answer:

Q. Simplify

1. 12x (22+3)

2. 10x (52-5)-4

3. 9+(23-4) +12-7

4. (102-42)-50 +9

5. 6x2+3-4+7

Ans. (using BODMAS)

1. 12×(22+3)

= 12×25=300

2. 10×(52-5)-4

= 10×47-4

=470-4=466

3. 9+(23-4)+12-7

= 9+19+12-7

=40-7=33

4. (102-42)-50 +9

= 60-50+9

= 69-50=19

5. 6×2+3-4+7

= 12+3-4+7

= 22-4=18

Answer 2

Answer :

1. 12 × (22 +3)

= 12 × 25

= 300

2. 10 × (52-5)-4

10×47-4

470-4

=466

3. 9+(23-4)+12-7

9+19+12-7

=33

4.(102-42)-50+9

60-50+9

=19

5.6×2+3-4+7

12+3+7-4

=18
