Get the algebraic expressions in the following cases using variables, constants and arithmetic 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) \[\frac{1}{2}(x+y)\] (iii) \[{{z}^{2}}\]                                (iv) \[\frac{1}{4}pq\]       (v) \[{{x}^{2}}+{{y}^{2}}\]                             (vi) \[3mn+5\] (vii) \[10-yz\]                     (viii) \[ab-(a+b)\]
