Answer:
2.437 + 0.0041 = 2.4411
0.4 - 0.063 = 0.337
Step-by-step explanation:
We can rewrite the numbers to be up to the same decimal point by appending 0s
2.437=2.4370
0.4 = 0.400
That's how fractions work, because 4/10 = 400/1000
After setting the same length, the addition or subtraction becomes very normal - just do it as you would always do
24370+41 = 24411, so 2.4370 + 0.0041 = 2.4411
400 - 63 = 337, so 0.400 - 0.063 = 0.337
