Here's something I learned, if that's a go math text book the answers are always in the last couple pages of the book
Answer:
18 and 42 are both multiples of 6, and when I add them, I also get a multiple of 6:
18+42=60.
Explain to Nina why adding two multiples of 6 will always result in another multiple of 6.
Step-by-step explanation:
18 and 42 are both multiples of 6 which means 6 is a factor of both numbers.
6⋅3=18
6⋅7=42

When you add 18 and 42, you can use the distributive property to show that the sum is also a multiple of 6:
6⋅3+6⋅7=6⋅(3+7)=6⋅10
