The minuend is the number being subtracted from.

A subtrahend is a number subtracted from another.

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

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

Identify the minuend and subtrahend in column subtraction

Maths

In this unit pupils will identify the minuend and the subtrahend in column subtraction and explain the column subtraction algorithm They will subtract from a 2-digit number using column subtraction with exchanging In the future unit pupils will use their knowledge of column addition column subtraction with exchanging to solve problems They will evaluate the efficiency of strategies for subtraction

In the prior unit pupils identified the addends and the sum in column addition. They used their knowledge of place value to correctly lay out column addition. In this unit pupils will identify the minuend and the subtrahend in column subtraction and explain the column subtraction algorithm. They will subtract from a 2-digit number using column subtraction with exchanging.
