Answer:
1. 68
2. 5
3.7684
4. 7
5. 37
Step-by-step explanation:
1. number 1 is equivalent to the expression 70 - 4 + 2 which is equal to 68
2. the net gain is equal to all the losses and gains added together, so 5 + (-2) + 6 + (-3) which simplifies to 5 - 2 + 6 -3 = 6
3.7677 - (-7) = 7684
4. this expression represents the scenario 12 - 3 - 2; which is equal to 7.
5. 60 - 8 - 15 represents the situation. this equals 37
