Question 2 Remove the brackets and write the expression having the same value. (a) 14 + (12 + 10) (b) 14 – (12 + 10) (c) 14 + (12 – 10) (d) 14 – (12 – 10) (e) –14 + 12 – 10 (f) 14 – (–12 – 10) Solving all of them (a) 14 + (12 + 10) = 14 + 12 + 10 (b) 14 – (12 + 10) = 14 – 12 – 10 (c) 14 + (12 – 10) = 14 + 12 – 10 (d) 14 – (12 – 10) = 14 – 12 + 10 (e) –14 + 12 – 10 = –14 + 12 – 10 (f) 14 – (–12 – 10) = 14 + 12 + 10 Rest no other expression is the same
