Question

In a game, Halley has 35 cards. This is 12 more cards than Felix. Write and solve an addition equation to find the number of cards Felix has.

Answer 1

As a subtraction problem it would be 35 - 12 = 23. But as an addition problem you can say ? + 12 = 35. In this situation the question mark would be 23. Hope this helps!!

Answer 2

X + 12 = 35 for addition
or you could do 35-12= x
