Rounded values get glued together

Time: 0:00

What it should do

addRounded(a, b) should add two numbers and return the result rounded to two decimal places, as a number. addRounded(1, 2) is 3.

What goes wrong

addRounded(1, 2) returns the string "1.002.00" instead of 3.

Hints

This is a mutation and copying bugs bug

Assignment does not copy, a shallow copy still shares its contents, and mutating methods return None.
