equations:
3 + 2 = 5
2 + 3 = 5                                                    Equivalent equations:
5 = 3 + 2                                                    3 + 2 = 4 + 1
5 = 2 + 3                                                    5 + 0 = 3 + 2


Missing addends:
3 + ? = 5
? + 2 = 5

Word Problems
