Question

How can I evaluate −x+| y | when x=13 and y=−7/4. how can I write this as a fraction in simplest form?

Answer 1

the | | sign is called a modulus, it means transform any number inside it to positive, so for example |-2| = 2 but |1| = 1.

therefore, -13 + |-7/4| = -13 + 7/4 = -52/4 + 7/4 = -45/4
