the meaning of the words "either ... or " in math problems.

Question

Use the digits shown on the number cubes below exactly one time each to create a four digit number than can be rounded to either 3,000 or 3,200.

Answer 1

Hint: You are asked to use the digits 1,4,5,3 to construct a number that rounds to 3200 (if you round to the 100s) or to 3000 (if you round to the 1000s). This requires the number to be $\geq 3150$ and $< 3250$.
