(b) Construct expressions using y, 2 and 7. ‘y’ is necessary in each expression. Use only two number operations, which are different.

Answer 1

(a) Possible expression, using t and 4 

(i) t + 4 

(ii) t – 4 

(iii) (t/4)

(iv) 4t 

(v) (4/t)

(vi) 4 – t

(b) Possible expression using y, 2 and 7 (operate only two different numbers) 

(i) 2y + 7 

(ii) 2y – 7 

(iii) 7y + 2 

(iv) 7y – 2 

(v) (y/2) - 7

(vi) (y/2) + 7

(vii) y + (2/7)

(viii) (y/7) + 2 and (y/7) - 2 e.t.c.
