infinity minus infinity is still infinity.

Also, there are different sizes of infinity.

For example, the infinite set of all integers (1, 2, 3, 4, 5, 6,...etc) is smaller than the infinite set of all real numbers (1.02, 5.00000005656737, 10,6743674673546, etc.) even though both sets are infinitely large.
