Definition for expression:

An expression is a mathematical statement which combines numbers and variables using mathematical operations. Expressions are used to find the value of missing information.

The basic mathematical expression begins with arithmetic. A mathematical statement like 4+7 is a simple basic mathematical expression. If it involves variables  (alphabets) it is called algebraic expressions. Algebraic expressions can be single variate or multi variate.

2x +3 is single variable expression.

2x + 3y + z is multi variable expression.

Now let us see some problems involving expressions.

1. 15 is decreased by z.

 (A)   15 - z (B)  z - 15 (C)  15z

2.6 less than twice y.

 (A)   y - 6 (B)  6 - 2y (C)  2y - 6

3.Difference between a and the product of x,y,f.

 xyf - a a - xyf axy - f

4.Twice p divided by 7.

 14p 7/2p 2p/7

5. T cubed divided by r.

 r / t³ t³ / r t³r

6. 3 times the difference between 2 and n.

 3 ( 2 - n ) 2 ( 3 - n ) 3 ( n - 2 )

7. U increased by , divided by X.

 X/U XU U/X

8.One fourth of p divided by 8.

 1/2 (p ÷ 8) 1/4 (p ÷ 8) 4 (p ÷ 8)

9. The sum of p,q and 4 times r.

 4r - p + q p - q + 4r p + q + 4r

10. product of x and y decreased by 10.

 10- xy xy - 10 10xy

1. 15 - z
2. 2y - 6
3. a - xyf
4. 2p/7
5. t³ / r
6. 3 ( 2 - n )
7. U/X
8. 1/4 (p ÷ 8)
9. p + q + 4r
10. xy - 10
