Mathematics

When adding 10 to any two digit number, increase the left digit by 1. For example 20+10= 30. 55+10=65. If a problem says 10+ (a number), you can reverse the order the numbers are in because of the commutative property of addition. Example: 10+50 eqauls 50+10. Both equations equal 60. Also, Rodney would have 39 pieces of fruit since 20+19 is 39.

It depends. Multiples of 10 are:
10, 20, 30, 40, 50...........
And a 2 digit number can be anything between 10 and 99.

To comment: Rodney would have 39 pieces of fruit.
