8)  Solve this BODMAS question

(17 × 18) ÷ 10 × 2(2 + 13) - 25

9)   Solve this BODMAS question

(3 + 3) × (3 ÷ 3) × (3 × 3)

10)  2550 - [510{270 - (90 - 80 + 70)}]

1)

 = 1800 ÷ 10{(12 - 6) + (24 - 12)}= 1800 ÷ 10{6 + 12}= 1800 ÷ 10 × 18= 180 × 18= 3240 Inner Brackets ( )Bracket { }DivisionMultiplication

2)

 = 1/2[{-2(1 + 2)10}15] × 3= 1/2[{-2(3)10}15] × 3= 1/2[-60 × 15] × 3= 1/2 × -900 × 3= 0.5 × -900 × 3= 1350 Inner Bracket ( )Inner Bracket { }Bracket [ ]DivisionMultiplication

3)

 = 20 - [6 - {4 - (8 - 6 + 3)}]= 20 - [6 - {4 - 5}]=  20 - [6 + 1]= 20 - 7= 13 Inner Bracket ( )Inner Bracket { }Bracket [ ]Subtraction

4)

36 ÷ 2 + y × 3 - 22 = 8

18 + × 3 - 22 = 8

18 + 3y - 22 = 8

3y - 4 = 8

3y = 8 + 4

3y = 12

y = 4

5)

= - (1/4 + 7/4) - 2

= - (8/4) - 2

= - 2 - 2

= - 4

6)

 = 45 × 3 × 7 × [22/11 + 36/12]By cross multiplication,=  45 × 3 × 7 × [(264 + 396)/132]=  45 × 3 × 7 × [660/132]=  45 × 3 × 7 × 5= 4725 Bracket, AdditionBracket, AdditionBracket, DivisionMultiplication

7)
