2. True or False

#### Task:
Determine whether the statements are true or false based on place value.

#### Example Problems:
1. 2 tens and 0 ones equals 52.
2. If you start counting in 2s from 35, your answer will end with 5.

#### Solutions:
1. False: 2 tens and 0 ones equals 20, not 52.
2. True: Counting in 2s from 35 gives: 35, 37, 39, 41, 43, 45, etc. All these numbers end with 5.

#### Explanation:
- Break down the numbers into their place values (tens and ones).
- For the second statement, observe the pattern when counting by 2s.
