Question

Form algebraic expressions to represent the following :-(a) product of numbers p and q subtracted from 10 (b) the sum of two consecutive numbers.

Answer 1

pq-10, answer of a
x,x+1, answer of b

Answer 2

First of all, you must know what 'Algebraic expressions' are? 

It is an mathematical expression involving integers, variable, operations etc. 


Now to answer your question. 

(a) product of numbers p and q subtracted from 10

We know that product of two no.s p and q will be equal to pq. Subtracting from 10, the expression will be = 10 - pq

(b) the sum of two consecutive numbers.

Let one number be x then the other number will be x + 1 (Consecutive integers)

The sum of these consecutive integers will be x+ x+ 1= 2x + 1
