Subtraction

Test what do you know about the subtraction of two numbers:
a) make a difference if the minuend 4,307,288 and subtrahend is 472008
b) minuend is 4000 more than subtrahend. What's the difference?
c) the difference is 38900 less than the minuend. What is the subtrahend?

Result

a =  3835280
b =  4000
c =  38900

Solution:

a=4307288−472008=3835280=3.835280⋅106a=4307288-472008=3835280=3.835280\cdot 10^{ 6 }
b=4000b=4000
c=38900c=38900
