To fill in the missing sign to make each equation true, we need to determine the arithmetic operation that makes sense in each case. Let's analyze each equation separately.
1) 160 ? 60 ? 4 ? 3 = 115
To find the missing signs, we can work through the equation step by step:
160 ? 60 = 220
220 ? 4 = 216
216 ? 3 = 213
So, the missing signs we need to fill in to make the equation true are:
160 + 60 - 4 - 3 = 115
2) 125 ? 5 ? 12 ? 2 = 1
Let's work out the equation step by step:
125 ? 5 = 130
130 ? 12 = 142
142 ? 2 = 71
So, the missing signs required to make the equation true are:
125 - 5 + 12 * 2 = 1
