Question

If there are 21 candies in the first jar, 32 in the second jar, and 43 in the third jar, how many candies are there in total?

Answer 1

Given, there are 21 candies in the first jar, 32 in the second jar, and 43 in the third jar.
So, the total number of candies = 21 + 32 + 43

Let’s use decomposition to expand the given numbers of candies.
21 = 20 + 1
32 = 30 + 2
43 = 40 + 3

Let’s now add all the tens and ones separately.
20 + 30 + 40 = 90
1 + 2 + 3 = 6
We get 9 tens and 6 ones.
90 + 6 = 96

So, 21 + 32 + 43 = 96
So, there are 96 candies in total.
