To represent the change in points, you can think of it in two ways:
1. You will go down 25 points for every wrong answer, so -25 + -25 + -25 would represent what is happening. They are all negative, so you keeping moving down in value.
2. You can also think of this as 3 groups of -25.
Both answers are -75. The answer is negative because the change was down in points.
-75 is the integer that represents this situation.
Step-by-step explanation:
15,729 = 10 000 + 5 000 + 700 + 20 + 9
= (1 x 10000) + (5 x 1000) + (7 x 100) + (2 x 10) + (9 x 1)
We can also write it like this :
(1 x 10⁴) + (5 x 10³) + (7 x 10²) + (2 x 10¹) + (9 x 10⁰)
5 × 9 = 45
