Imagine you are counting the number of students in your class. If there are 26 students and one new student joins, you now have 27 students. So, 27 is just one more than 26.

Worked Example

Step-by-Step

Let's say your mother bought 2 dozen (2 x 12 = 24) bananas from the market. --- Then, your neighbour gave her 3 more bananas. --- To find the total number of bananas, you would add the bananas your mother bought and the bananas your neighbour gave. --- So, 24 + 3 = 27. --- Your mother now has 27 bananas in total.

Common Mistakes

MISTAKE: Confusing 27 with 72 | CORRECTION: Remember that the '2' in 27 means twenty, while the '7' means seven. In 72, the '7' means seventy.

MISTAKE: Thinking 27 is an even number | CORRECTION: An even number can be divided by 2 without a remainder. 27 divided by 2 leaves a remainder of 1, so it is an odd number.

MISTAKE: Skipping 27 when counting by ones | CORRECTION: Always count carefully: 25, 26, 27, 28. Don't miss any numbers in sequence.
