Give an example of two negative numbers whose modulus of sum is 4.
| August 16, 2021 | education
To solve this problem, remember that the modulus of a negative number is equal to the opposite number.
| −a | = a, if a <0. Based on this, we give an example:
1) If a = -1, b = -3, then
| a | + | b | = 1 + 3 = 4
2) If a = -2, b = -2, then
| a | + | b | = 2 + 2 = 4
Answer: a = -1, b = -3; a = -2, b = -2.
