Examples – Solutions to Odd Numbered:

Problem 1:

Add: 21 + 25 = 46

Subtract: 55 – 23 = 32

Multiply: 13 * 19 = 247

Divide: `545 / 5` = 109

Problem 2:

The number 31 is odd number. Because the last digit is 1
The number 453 is odd number. Because the last digit is 3
The number 4625 is odd number. Because the last digit is 5
The number 48347 is odd number. Because the last digit is 7
