**Reiny**, Tuesday, September 17, 2013 at 8:01amUse your scientific calculator

the operations of**log**and**10^x**, which should be found on your calculator, are inverses of each other

e.g

suppose you want log 35.5

on mine the key strokes are as follows:

log

35.5

=

to get 1.55022...

Now you want antilog 1.55022

which is really just 10^1.55022...

so you could use the**y^x**key

such as

10

y^x

1.55022...

=

to get back the 35.5

or

2ndF

log

1.55022...

=

to get 35.499999.... (which is 35.5 for all practical purposes)

practise the above using some different values.
