Answer :
Let's go through each subtraction problem step-by-step:
a) Subtract 0 from -218
To subtract 0 from any number, the result is the number itself. So when you subtract 0 from -218, the result is:
[tex]-218 - 0 = -218[/tex]
b) Subtract -218 from 0
When you subtract a negative number, it's the same as adding the opposite of that number. So, subtracting -218 from 0 is the same as adding 218 to 0:
[tex]0 - (-218) = 0 + 218 = 218[/tex]
c) Subtract 218 from 218
Any number subtracted from itself results in zero. Therefore, subtracting 218 from 218 gives:
[tex]218 - 218 = 0[/tex]
d) Subtract -218 from -218
Subtracting a negative number is the same as adding the positive equivalent. Therefore, subtracting -218 from -218 is like adding 218:
[tex]-218 - (-218) = -218 + 218 = 0[/tex]
e) Subtract 218 from -218
Here, we are subtracting 218 from a negative number, which results in increasing the negative value:
[tex]-218 - 218 = -436[/tex]
f) Subtract 999 from -999
Subtracting a positive number from a negative number also increases the negative value:
[tex]-999 - 999 = -1998[/tex]
