The height of the Egyptian pyramid is about 140 meters, 121 meters lower than when it was built. How many meters higher was it when it was built?


140 (1-121) = 140 (2021) = 147 (m) a: 147 m high when completed



If a is a rational number, then there must be an absolute value of a - a = 0


No, if a is positive, - A is negative
