Worksheet on Subtraction of Unlike Terms

Practice the questions given in the worksheet on subtraction of unlike terms. We know that, the difference between one like term from the other like term can be express as a single like term but in case of unlike terms we cannot subtract them from one another to express the result as a single term.


1. Find the difference of:

(i) 9n from 13m

(ii) 7a2 from 7ab

(iii) 5a2 from 11a2b

(iv) 4n from 9mn

(v) 9x3 from 15x2

(vi) zx2 from x2y

2. Subtract the following:

(i) from 5pq take p

(ii) from 11a2bc take 5abc

(iii) from -9bc take 9ac

(iv) from x2 take y2

(v) from 17mn take 9n

(vi) from 21xy take 21ab


3. Subtract the first term from the second term:

(i) 9a, 11b

(ii) 7ab, 3b2

(iii) 5y, 3x

(iv) 11mn, 21m

(v) pq, ab

(vi) 23pqr, 23pq


4. Evaluate the following:

(i) 2x + 5y - 3y

(ii) a + b + a - b

(iii) 6xy - 8y - 3xy

(iv) 8x - 5y - 7x + 10y

(v) -5ax - 9ax - 7ay

(vi) x2 - y2 - x2


5. What is the difference between -11pq and 9p?

6. How much is 7m + 5n greater than 3n?


Answers for the worksheet on subtraction of unlike terms are given below to check the exact answers of the above questions on subtracting unlike terms.
