Answer:An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 512, and √2 are not. ... ℤ is a subset of the set of all rational numbers ℚ, which in turn is a subset of the real numbers ℝ.

First, add the numbers in the hundredths column:
9+8=16
Carry the one, and add the numbers in the tenths column:
1+0+3=4
Now, add the numbers in the ones column:
1+1=2
Bring the decimal straight down.
The answer is 2.46
