## Lesson details

### Key learning points

1. The minuend is written first in a column subtraction.
2. The subtrahend is written beneath the minuend.
3. The difference is recorded underneath the minuend and subtrahend, with the same value digits in the same column.

### Common misconception

Pupils may struggle when horizontal calculations do not present the minuend at the beginning of the equation (e.g. 23 = 44 - 21).

Discuss with pupils the minuend as the whole. It is the number being subtracted from. In a column subtraction, we always write the minuend first but it does not always appear first in horizontal calculations.

### Keywords

• Minuend - The minuend is the number being subtracted from.

• Subtrahend - A subtrahend is a number subtracted from another.

• Difference - The difference is the result after subtracting one number from another.

• Column subtraction - Column subtraction is a way of subtracting numbers by writing a number below another.
