Answer:One of the lesser-known features of Excel is its ability to automatically generate subtotals on multiple levels using the application's Subtotal feature. If you keep sales figures in your worksheet, for example, you can create subtotals for sales in each region, plus nested subtotals broken down by state and even city. To implement multiple-level subtotals, first use Excel's advanced sorting function to rearrange your data into the right grouping levels.

Answer:
(a) Onto
(b) Not onto
(c) onto
(d) onto
Explanation:
Let, A = Z × Z and B = Z
(a) f(m,n) = 2 m - n
An integer can be written as 2 times of another integer minus any third integer.
Thus, for every element of B there is a pre-image in A.
i.e, f is onto.
(b)
Since, there are lots of integers that can not obtain after subtracting the squares of two integers,
For eg : 1, 2, 4,..... etc
Thus, for these elements there is not any pre-image in A,
I.e. f is not onto.
(c) f(m,n) = m + n + 1
,
An integer can be written as the sum of two integers and 1.
Thus, for every element of B there is a pre-image in A.
i.e, f is onto.
(d) f(m,n) = |m| - |n|
|x| = x if x > 0
While, |x| = -x if x < 0,
Thus, both |m| and |n| are always positive,
Every integer can be written as the difference of two positive integers.
Thus, for every element of B there is a pre-image in A.
i.e, f is onto.
