Question:
9. Use the sign of >, < or = in the box to make the statement true.
(a) 25 + 40 - 10 ____ 25 - 40 - 10
(b) (-9) + (-6) ____ (-9) - (-6)
(c) 5 - 4 + 10 ____ 2 - 6 - 10
(d) 6 + 1 - 3 _____ 10 - 2 - 4
10. Solve the following:
(i) 2 × (1 + 2) = (2 × 1) + (2 × 2)
(ii) 5 × (3 + 2) = (5 × 3) + (5 × 5)
[tex]\implies[/tex] (25 + 40) - 10 _____ 25 - (40 + 10)
[tex]\implies[/tex] 65 - 10 _____ 25 - 50
[tex]\implies[/tex] 55 _____ - 25
On comparing we get,
[tex]\implies[/tex] 55 > 25
We know that —
[tex]\implies[/tex] - 9 - 6 _____ - 9 + 6
[tex]\implies[/tex] - 15 ____ - 3
[tex]\implies[/tex] - 15 < - 3
[tex]\implies[/tex] (5 + 10) - 4 _____ 2 - (6 + 10)
[tex]\implies[/tex] 15 - 4 _____ 2 - 16
[tex]\implies[/tex] 11 ____ - 14
[tex]\implies[/tex] 11 > - 14
[tex]\implies[/tex] (6 + 1) - 3 _____ 10 - (2 + 4)
[tex]\implies[/tex] 7 - 3 ______ 10 - 6
[tex]\implies[/tex] 4 _____ 4
[tex]\implies[/tex] 4 = 4
Solve the brackets,
[tex]\implies[/tex] 2 × 3 = 2 + 4
[tex]\implies[/tex] 6 = 6
[tex]\implies[/tex] 5 × 5 = 15 + 25
[tex]\implies[/tex] 25 = 40
[tex]\implies[/tex] 25 ≠ 40
Applied rule: B O D M A S
: → B = Brackets
: → O = Order
: → D = Division
: → M = Multiplication
: → A = Addition
: → S = Subtraction

(i) 2 × (1 + 2) = (2 × 1) + (2 × 2)
(ii) 5 × (3 + 2) = (5 × 3) + (5 × 5)
Answer 9:
Step-by-step explanation:
(a) 25 + 40 - 10 ____ 25 - 40 - 10
[tex]\implies[/tex] (25 + 40) - 10 _____ 25 - (40 + 10)
[tex]\implies[/tex] 65 - 10 _____ 25 - 50
[tex]\implies[/tex] 55 _____ - 25
On comparing we get,
[tex]\implies[/tex] 55 > 25
(b) (-9) + (-6) ____ (-9) - (-6)
We know that —
[tex]\implies[/tex] - 9 - 6 _____ - 9 + 6
[tex]\implies[/tex] - 15 ____ - 3
On comparing we get,
[tex]\implies[/tex] - 15 < - 3
(c) 5 - 4 + 10 ____ 2 - 6 - 10
[tex]\implies[/tex] (5 + 10) - 4 _____ 2 - (6 + 10)
[tex]\implies[/tex] 15 - 4 _____ 2 - 16
[tex]\implies[/tex] 11 ____ - 14
On comparing we get,
[tex]\implies[/tex] 11 > - 14
(d) 6 + 1 - 3 _____ 10 - 2 - 4
[tex]\implies[/tex] (6 + 1) - 3 _____ 10 - (2 + 4)
[tex]\implies[/tex] 7 - 3 ______ 10 - 6
[tex]\implies[/tex] 4 _____ 4
On comparing we get,
[tex]\implies[/tex] 4 = 4
Answer 10:
Step-by-step explanation:
(i) 2 × (1 + 2) = (2 × 1) + (2 × 2)
Solve the brackets,
[tex]\implies[/tex] 2 × 3 = 2 + 4
[tex]\implies[/tex] 6 = 6
(ii) 5 × (3 + 2) = (5 × 3) + (5 × 5)
[tex]\implies[/tex] 5 × 5 = 15 + 25
[tex]\implies[/tex] 25 = 40
[tex]\implies[/tex] 25 ≠ 40
