calculate the difference between negative and positive values

I need to show the difference between costings for last month, compared
with this month.

For example, last month a particular costing showed a profit of \$100.
This month is showing a loss of -\$200. I need to show that this month
the difference between the costings is therefore -\$100, or, \$100
dollars less than last month.

Can anyone offer me the formula to do this?

Sneaky second question!... it would be useful to display, in the above
example, "\$100 less", rather than "-\$100". Can this be done?

Many thanks

When I went to school:

100-(-200)=100+200=300

[If it was \$100 dollars less it would be 0 (zero) this month]

so I contend the difference is \$300 so the formula is:

=A1-B1 A1=Last month, B1=This Month

=IF(B1-A1<0,ABS(B1-A1) & " less",IF(B1-A10,B1-A1 & " more",B1-A1))

A1/B1 as above

Ah, the difference is -\$300, not -\$100. The signed difference is
"newValue - oldValue". By "signed difference", I mean: negative for
less; positive for more. In this case, (-200) - 100 = -300. If
"oldValue" is in A1 and "newValue" is in A2, the difference (A3) is:

=A2 - A1

Sneaky second question!... it would be useful to display, in the above
example, "\$100 less", rather than "-\$100". Can this be done?

In A3:

=if(A2-A1 < 0, text(A1-A2,"\$0") & " less", if(A2-A1 0,
text(A2-A1,"\$0") & " more", "no change")

Note the reverse order "A1-A2" in the "less" case. This produces a
positive number like "\$100 less" instead of a negative result like
"-\$100 less".

Thanks for those very useful responses - I have been able to solve the
problem.

One question following - using your suggested formulas I am also
setting up fields to show that, for example, this month employee A is
working for 1 hour 20 minutes longer that last month. This value is
expressed as a decimal, i.e. the employee is working 1.33 hours more.

The formula however only returns "1 hour more" and does not recognise
the fractional part of the number. How can I adjust the formula to
display this.

Many thanks (and sincere apologies for my terrible maths in the
original question!)
