Which of the following equals two? Is it five take away four, six take away three, four take away three, or six take away four?

Which of these calculations gives us an answer of two? Is five take away four two? Here, we have five counters. And we need to take away four. One, two, three, four. How many counters do we have left? Five take away four equals one. So this is not the correct answer. Does six take away three equal two? So here we have six counters. And we need to take away three. One, two, three. There are three counters left. Six take away three equals three.

Does four take away three equal two? So we have four counters. And we need to take away three. One, two, three. That’s one counter left. Four take away three is one. This means that six take away four must equal two. This is the only choice we have left. So we have six counters. And we need to take away four. One, two, three, four. There are two counters left. Six take away four equals two. We worked out each of the answers and found that six take away four equals two.
