Default Fun With That Wages Book Again

Thanks Yacbo! Your reply is appreciated,

Yea, you got me on the typo. Sorry.

As for the parenthesis, sometimes they are necessary and sometimes not. For
instance, the expression A + B * C gives the exact same result as A + (B * C)
and the parenthesis are superfluous. But they do serve the purpose of
allowing me to follow what I am trying to accomplish. For example, a change
of the placement of the parenthesis to (A + B) * C produces an entirely
different result. In this case, the parenthesis are important because I’m
telling Excel to add A to B first and then multiply by C, which it would not
normally do. This is in stark contrast to the first example in which I am
telling Excel to multiply B and C and then add the product to A which is what
Excel would normally do with or without the parenthesis. In both examples, I
am telling Excel explicitly what I want done without relying on its rules of
math order. As long as you are well versed in mathematical protocol, you may
feel free to forgo the extra parenthesis, but do be careful.

Thanks again, Yacbo.
It took me a while to work out what you were at in this one.
I think there is a typo and you mean 0.06 in I9, not 0.04.
Anyway I see what you mean.
Thanks for explaining it. What's the significance of double and even treble
parentheses?

Oops, last number in my example (in cell K9) should read: 30.92. Got a
little ahead of myself. Sorry.

Sure, you can switch ((G9-127)*0.04) with (0.04*(G9-127)) and mathematically,
it makes no difference, which begs the question why do it? But you can’t
switch ((G9-127)*0.04) with (G9-127)*0.04)) which is what you have done.
Actually, due to the order of math, you could leave out the outer parenthesis
in my formula and just type (G9-127)*0.04 or 0.04*(G9-127) instead and it
wouldn’t matter. I just include additional parenthesis to make it neater.
Your error is coming from the improper placement of the parenthesis.

But let’s make this easier by using helper columns. Below, I start with a
raw number in cell G9. For the other cells (H9-K9), the computed number is
shown and the formula that got us there is listed below.

600 0 18.92 30.92 28.38
(raw) (1) (2) (3) (4)

Formulas:

(1) =0*G9
(2) =(G9-127) * 0.04
(3) =127*0.02 + (G9-127)*0.04
(4) =IF(G9=300,H9,IF(G9=440,I9,J9))

This method should also work with your SI coding. Using the helper columns
lets you see what is happening. Type these formulas into a blank Excel sheet
and then change the raw number to various samples from your range to see the
result in cell K9.

Not at all, Yacbo. you were a great help to me with my original question.
It's just I feel I know nothing. I did the online demos from Microsoft on
Excel. I could understand them and do the practicals. It's like learning to
drive in a car park; - so easy, and then being put on to a highway during
rush hour. Totally haven't a clue how to do anything! For example: You gave
me the following formula and it works great for me:
=IF(G9=300,0,IF(G9=440,(0.04*(G9-127)),(2.54+(G9-127)*0.06))).
Then, Yacbo, I was putting it in somewhere else and I moved the '0.04',
didn't I? And it wouldn't work. And I don't know what difference I am making
to how the formula works:
=IF(G9=300,0,IF(G9=440,(G9-127)*0.04)),(2.54+(G9-127)*0.06)))
It won't work that way. I get the error message.

Then I have the following: =IF(G9=300,"AO",) Works Fine
=IF(G9=356,"AX",) Works Fine
=IF(G9=440,"AL",) Works Fine

But I can't join them together in one formula. I've tried putting in double
parentethis like in your formula. Can't get it to work. "AO", "AX","AL" are
NOT cell no's, they are references in the Social Insurance system. I also
wanted to include in the formula that anything over 440 was to be "A1" (A
letter and a figure) but I'm not sure Excel will let me go to 4 'IF's' in the
one cell.
At this stage I feel I'd be better writing everything by hand and just using
a calculator, such is my frustration.

To be honest, I'm kind of new to this forum and just learning my way around.
Kassie has apparently been most helpful to you as has Gord. These guys are
vastly superior to my humble abilities and perhaps one of them will weigh in
and answer your question. For my part, I don't quite understand the current
question, but stand willing to help in any way possible. To that end, I have
two suggestions: First, do another post being more specific as to what the
input and output are and why the formulas are not working. And two, you
might submit your post to the category of Excel"Worksheet Functions" in
addition to this room. Please don't consider this latter suggestion as
diversionary-- I just think you might be depriving yourself of a valuable
resource in the folks that regularly help over in the "Worksheet Functions"
room in which I have gained many helpful tips. I would like to stress that
the people who offer help in all these communities are top notch. I feel
guilty that I help so little and gain so much from people like Kassie, Gord,
and many others! Thanks to all.

Thanks, Yacbo!
I still get stuck. Kassie has been a great help, though. I still have
problems in other columns with them being filled in all the way down with
'incorrect' figures until I make an entry. When I make an entry it corrects
the figure in the adjacent cell to which it refers but the rest, all the way
down should not be there. It drives me mad. It doesn't happen with the
Formula Kassie gave me, though (=IF(G9="","",H10+G9). Can I call on you guys
again or will I drive you all mad?

G H

422.00 1742.00 (G12+H11)
1742.00
1742.00
I have to type in the formula in H each time I make an entry in G in order
to get H to complete. If I drag the auto complete down it fills in the last
entry all down the column, which I don't want to happen. Why doesn't excel
recognise what I'm at and just fill in column H for me? Although the above
example only shows four entries, it's the same after seven. The Autocomplete
box is ticked.
Help anyone? - Gatsby
