1.	Get the algebraic expressions in the following cases using variables, constants andarithmetic operations.(i) Subtraction of z from y.(ii) One-half of the sum of numbers x and y.(iii) The number z multiplied by itself.(iv) One-fourth of the product of numbers p and q.(v) Numbers x and y both squared and added.(vi) Number 5 added to three times the product of numbers m and n.(vii) Product of numbers y and z subtracted from 10.(viii) Sum of numbers a and b subtracted from their product.
Answer» (i) `y-z` (ii) `(x+y)/2` (iii) `z xx z =z^2` (iv) `pq1/4 = (pq)/4` (v) `x^2+y^2` (vi) `3mn+ 5` (vii) `10-yz` (viii) `ab-(a+b) = ab- a-b` answers
