The MIT mathematics tests... out of context and "unequal" is no correct.
If I have to buy some milk, one liter. I need shoes, clothes, a supermarket near by and the price of the milk, which must equal the amount of money in either my wallet or debt card. X is how much money I need.
In this context X is not only equal, but both equal or equal greater.
Every Greek of the Antique who stated that mathematics describes the world will just node here and as I refuse taking the test as you did not understand mathematics.
They argue??
Bullets now anyone ... ???
