Question 1.
Fill in the blanks with numbers, and boxes with operation signs such that the expressions on both sides are equal. Class 7
(a) 24 + (6 – 4) = 24 + 6 _____
(b) 38 + (_____ ☐ _____) = 38 + 9 - 4
(c) 24 - (6 + 4) = 24 ☐ 6 - 4
(d) 24 - 6 - 4 = 24 - 6 ☐ _____
(e) 27 - (8 + 3) = 27 8 3
(f) 27 - (_____ ☐ _____) = 27 - 8 + 3
Solution:
(a) 24 + (6 - 4) = 24 + 6 - 4
(b) 38 + (9 - 4) = 38 + 9 - 4
(c) 24 - (6 + 4) = 24 - 6 - 4
(d) 24 - 6 - 4 = 24 - 6 - 4
(e) 27 - (8 + 3) = 27 - 8 - 3
(f) 27- (8 - 3) = 27 - 8 + 3
Question 2.
Remove the brackets and write the expression having the same value. Class 7
(a) 14 + (12 + 10)
(b) 14 - (12 + 10)
(c) 14 + (12 - 10)
(d) 14 - (12 - 10)
(e) -14 + (12 - 10)
(f) 14 - (-12 - 10)
Solution:
(a) 14 + (12 + 10) = 14 + 12 + 10 = 36
(b) 14 - (12 + 10) = 14 - 12 - 10 = -8
(c) 14 + (12 - 10) = 14 + 12 - 10 = 16
(d) 14 - (12 - 10) = 14 - 12 + 10 = 12
(e) -14 + 12 - 10 = -14 + (12 - 10) = - 12
(f) 14 - (-12 -10) = 14 + 12 + 10 = 36
