I had already given you a hint for another way we can do our subtraction. Can you think of what it is? That’s it. We can use place value columns. Place each of the numbers in their correct column. Sixteen is one ten and six ones. So the one goes in the tens column and the six goes in the ones column. Four is four ones so it goes in the ones column. We can see in the ones column that we have six take away four and the answer is two. In the tens column we have one take away nothing. Can you tell me what this leaves? It leaves one. We can also write it a quicker way. Like this. Sixteen take away four equals twelve. Make sure you keep the numbers in the correct columns. This will help you when you’re working.
