Pricing science is like a kind of math. Experts figure out the right prices for things. They use special formulas and compare prices to other similar things or different things that people might want to buy, then they figure out how much something should cost. For example, if there are two computers, they might compare the specs on the computers, like how much RAM and storage each one has. Then they can figure out which one should cost more so that it's fair for both the person selling the computer and the person buying it.
