Answer:
42-38
42 + (-38)
-38+42
Step-by-step explanation:
In all of these expressions, the 38 has to be negative because that is what you're taking away from the 48. When you have -(- it turns into a +.
In -42 + 38 the 42 is negative, but that is Emma's total amount so it's positive
With -42 -(-38) they did the just added those two together which would make the 42 still negative and the 38 positive.
THen with 42 + 38 the 38 is being subtracted from what she has so you would not add 38 to her total.
