What to Focus On

  • Shabnam's age is 3 years more than Aftab's age.
  • Aftab's age is 3 less than Shabnam's age.
  • Letters used to represent numbers are called letter-numbers.
  • Swapping terms does not change the value of an expression.
  • Grouping terms in a convenient way does not change the value of an expression.
  • Brackets help show order clearly.
  • The multiplication sign is omitted in algebraic expressions.
  • The number is written before the letter.
  • n can represent the position in a sequence.

Common Mistakes to Avoid

A letter-number is just a random letter and cannot stand for a number.

The expression a + 3 and 3 + a are different in value.

The expression 4n means 4 + n.
