Which picture shows five take away four equals one?

In this question, we’re given a subtraction equation or a number sentence. An equation or a number sentence is a way of showing a number fact using numbers and symbols. In this particular number sentence, we can see the number five then this symbol that looks like a short line. This is the symbol for taking away or subtracting. Then, we have the number four. This is the number that we need to take away.

Then, we can see the equal symbol. And after that comes the answer. This is the amount that we have left. We can read this number sentence as five take away four equals one. So, which picture shows five take away four equals one? And as we’ve said already, the number five represents the number that we’re starting with. Let’s go through each of our pictures to see which one contains five objects to begin with.

Our first picture shows one, two, three doughnuts. This picture doesn’t start with five, does it? Let’s look at the group of dogs. We have one, two, three, four, five dogs. This picture could show five take away four equals one. In our second set of doughnuts, there are one, two, three, four, five. This could be the correct one. Then, we have a group of one, two, three, four sweets. This is too small. And our final picture shows one, two, three, four, five sweets. So, the picture that we’re looking for is either the row of dogs, the longer row of doughnuts, or the longer row of sweets because they all contain five objects to start with.

The second number in our subtraction equation is the number four. And this shows us the number that we need to take away. In these pictures, we can see the objects that have been taken away because they’ve been crossed through. How many dogs have been taken away? One, two. The picture of the dogs shows the subtraction five take away two. What about the long row of doughnuts? We’ve taken away one, two, three, four. This shows the subtraction five take away four. This is the subtraction we’re looking for. Looks like this is going to be our answer. Let’s just check the row of sweets.

Well, if we look, we can see that only one sweet has been crossed out. This shows the subtraction five take away one. The last number in our number sentence is one. Five take away four equals one. And we can see in our row of doughnuts that this is true. Five doughnuts take away four doughnuts leaves us with one doughnut. The picture that shows five take away four equals one is the row of doughnuts that shows five doughnuts with four of them crossed out and one left over.
