Use this working out to show the answers for the other beads:
1.
There are two rows.
There are 5 beads in each row.
5+5= 10
5x2= 10
2. There are two rows.
There are 7 beads in each row.
7+7= 14
7x2= 14
Example: 5 + 5 is the same as 2 x 5= 10
- 6 + 6 is the same as 2 x 6= 12
- 7 + 7 is the same as 2 x 7= 14
- 7 + 7 is the same as 2 x 7= 14
- 8 + 8 is the same as 2 x 8= 16
- 9 + 9 is the same as 2 x 9= 18
- 10 + 10 is the same as 2 x 10= 20
Example: If 2 x 3= 6 then 4 x 3= 12
- If 2 x 4= 8 then 4 x 4= 16
- If 25 x 2= 50 then 25 x 4= 100
- If 2 x 40= 80 then 4 x 40= 160
- If 2 x 7= 17 then 20 x 7= 140
