Swati had 24 beads. She needs 8 more beads to make a necklace.

How many beads are used in a necklace?

To know the total number of beads, let us find the sum of 24 and 8.

First arrange the numbers one below the other according to their

place value.

Step 1. Add the ones and regroup. Step 2. Add the tens.

4 + 8 = 12 ones = 1 ten 2 ones 1 + 2 = 3 tens
Write 2 in the ones column and Write 3 in the tens column.

carry over 1 to the tens column. t O

t O 1
1 2 4
2 4 + 8
+ 8 3 2

2

Thus, 24 + 8 = 32. So, Swati is using 32 beads in a necklace.
