Using the given model, find 28 plus
46.
In this question, we’re adding two
two-digit numbers. The number 28 has two 10s and eight
ones, and the number 46 has four 10s and six ones. Let’s use a place value chart to
help us add. When we’re adding two two-digit
numbers, we always start by adding the ones. 28 has eight ones. 46 has six ones. Eight ones plus six ones gives us a
total of 14 ones. We need to regroup 10 of our ones
and make one 10. Our 14 ones make a group of 10 and
four ones.
Now that we finished adding the
ones and regrouping, we need to add our tens. 24 has two 10s, and 46 has four
10s. We’ve got seven 10s altogether and
four ones. Seven 10s are worth 70, plus four
ones make 74. 28 plus 46 equals 74.
