# what does it mean to write the doubles fact you used to solve problem 0+1

This is first grade math - no other directions were given.

I assume that this is meant to illustrate that zero added to a number does not change the number.

Doubles are number sentences the use the same number to added twice. 2+2=4, once they know this by hard. they use the knowledge to solve 2+3= ?, knowing that 2+2=4 and that 3 is 1 greater than 2, the logical conclusion is that the answers is 1 more than 4 which is 5.
