Complete the following: 60 subtract
what equals 10.

In this question, we have to find
the missing number. In other words, what do we need to
subtract from 60 to leave us with 10? We can use six 10s to model the
number 60. 10, 20, 30, 40, 50, 60. Let’s take away 10s until we’re
left with 10. We have 60. If we take away one 10, we’re left
with 50. If we take away two 10s, we have 40
left. If we take away three 10s, we’re
left with 30. If we take away four 10s, we have
20 left. And if we take away five 10s, we
have 10 left.

How much did we take away
altogether? Five 10s are 10, 20, 30, 40,
50. If we have six 10s or 60 and we
take away 50, we’re left with 10. The missing number is 50.
