10 Base Systems p.86~p.87 1 Each bead on the bottom represents 1 and each

bead on the top represents 5.

Therefore, 531 264 267.

Example 2, 2, 10, Bread 4, 2, 4, 2, 6, June 2 Each grid represents the following numbers.

16, 4, 1, 16, 4, 1, 21, 21st

TryItAgain Type of product : 8 1 9 64 16 4 1
Month of manufacture : 4 1 5 64 16 4 1
Day of manufacture : 4 2 1 7 64 16 4 1
Type of product : Jam
Date of manufacture: May 7th Therefore, 36 65, so 29.

29 16 4 4 4 1, so color one 16 square,

three 4 squares, and one 1 square.

Example 1 g 1 6 g 9 3 11 g 9 3 1
2 g 3 1 7 g 9 3 1 12 g 9 3
3 g 3 8 g 9 1 13 g 9 3 1 Type 10-2 Finding Patterns and Calculating p.90~p.91

2, 3, 4, 9, , 3, , , 9, 1, , 9, 3, 1 2 The numbers are carried over when they reach
5, so it is a base 5 number system.
Type 10-1 The Represented Number p.88~p.89
1 1, 1, 3, 3, 9, 9 1
2 5, 15
3 1, 9, 9, 20 204

3 The pattern uses a base 5 number system, so
calculate by borrowing 5.
