Question 1 Fill in the blanks with numbers, and boxes with operation signs such that the expressions on both sides are equal. (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 Let’s try to do this (a) 24 + (6 – 4) = 24 + 6 – 4 ∴ (a) 24 + (6 – 4) = 24 + 6 4 (b) 38 + ( ___ ___) = 38 + 9 – 4 = 38 + (9 – 4) ∴ (b) 38 + (9 4) = 38 + 9 – 4 (c) 24 – (6 + 4) = 24 – 6 – 4 ∴ (c) 24 – (6 + 4) = 24 6 – 4 (d) 24 – 6 – 4 = 24 – 6 – 4 ∴ (d) 24 – 6 – 4 = 24 – 6 4 (e) 27 – (8 + 3) = 27 – 8 – 3 ∴ (e) 27 – (8 + 3) = 27 8 3 (f) 27 – ( ____ ____) = 27 – 8 + 3 = 27 – (8 – 3) ∴ (f) 27 – ( 8 3) = 27 – 8 + 3
