Addition And Subtraction Of Algebraic Expression
6. Collect like terms and simplify the expression:
12m2 9m + 5m 4m2 7m + 10
Solution: Rearranging terms, we have:
12m2 4m2 + 5m 9m 7m + 10
= m2 + m + 10
= 8m2 + m + 10
= 8m2 + m + 10
7. Subtract 24ab 10b 18a from 30ab + 12b + 14a.
Solution: 30ab + 12b + 14a
= 30ab + 12b + 14a 24ab + 10b + 18a
= 30ab 24ab + 12b + 10b + 14a + 18a
= 6ab + 22b + 32a
8. Find the value of x2-5x+8, for x = 2.
Solution: Given: x2-5x+8
= 2 5 + 8

Algebra Questions For Class 6
Basic algebra deals with finding the unknown value using variables.
1. Soldiers are marching in a parade. There are 10 soldiers in a row. What is the rule which gives the number of soldiers, given the number of rows?
Solution: Let n be the number of rows
Number of soldiers in a row = 10
Total number of soldiers = number of soldiers in a row × number of rows
2. Leela is Radhas younger sister. Leela is 4 years younger than Radha. Write Leelas age with respect to Radhas age. Take Radhas age to be x years.
Solution: Let Radhas age be x years
Leelas age = 4 years younger than Radha
3. If a is the side-length of the equilateral triangle, then the perimeter of the triangle will be?
Solution: Side of equilateral triangle = a
The perimeter of triangle = sum of all its three sides
Since we know that an equilateral triangle has all its sides equal.
Perimeter of equilateral triangle = a+a+a = 3a

How To Solve Algebraic Questions
When you are presented with an algebraic problem it is important to establish what you are being asked to do. Here are some of the key terms along with what they mean:
- Solve the equation find out the value of the unknown
- Substitute put the values you have been given into the algebraic expression
- Simplify collect together like terms to make the expression or equation look simpler
- Expand brackets multiply out the brackets
- Factorise put into brackets
- Make x the subject rewrite the equation in the form x =..
Remember, when working with algebra, we must still apply BODMAS / BIDMAS. i.e. Brackets, Indices , Division, Multiplication, Addition, Subtraction.
When working with algebraic expressions and equations we must consider carefully which operations to deal with first.
