A set is simply the group of numbers.
- <em>The set of M and N are: </em>
<em> and </em>
<em>.</em> - <em>The set of M n N is: </em>
<em>.</em> - <em>The set of M u N is: </em>
<em />
<u>(a) The set of M and N</u>
Given that:
M = squares of integers less than 100
N = Positive odd numbers less than 15
So, we have:

<u>(b) M n N and M u N</u>
M n N is the set of common elements between sets M and N.
So, we have:

M u N is the set of all elements in sets M and N.
So, we have:

Well a difference is the difference between them. difference means subtraction. So so a difference can be written as:
40.67 - (-41.29)
If you subtract a negative number you really add it. to make sense of this you could say 40.67 is 40.67 units away from zero in the positive direction. whereas -41.29 is 41.29 units away in the negative direction. since they go in opposite directions away from zero that means that thw length between them is extended and must then be added together. So
40.67 + 41.29 = 81.96
