Enter only the numerals, not the letters.
^Top What features do our calculators have?
The attached chart shows comparisons of the different calculator models. This includes graphing, scientific and printing calculators. download the chart here
^Top What is the [F CUT 5/4] switch or [DEC] F, 0, 2 button for?
The HR-8TE/HR-8TM have a [DEC] key with F, 0, 2, and 5/4 over it, while many other calculators models have a switch labeled [F CUT 5/4].
The button or switch can control rounding off to a certain number of decimal places. F is floating point (no F indicator on screen), 0 rounds off to 0 places after decimal point, and 2 rounds off to 2 places after decimal point.
The 5/4 applies to either the 0 or 2 modes, and describes the type of rounding off that is performed. The calculator will round down if the digit after the one you are rounding to is 4 or lower, and round up if the digit is 5 or higher.
^Top What is the [5,4,3,2,1,0 ADD (2)] switch used for?
This switch is used to determine how many decimal places your answer is displayed in.
ADD (2) is often used for monetary calculations, so that it is not necessary to enter the decimal point. It is automatically placed two decimal places from the end for cents. For example, entering 123 will display as 1.23.
^Top Why do I get 111.1111... when I calculate 100+10%?
This is a markup on price procedure. The formula is as follows:
Markup%=(Markup Price-Cost)/(Markup Price)
^Top Why do I get the wrong answer when doing a percent calculation?
Make sure that you are following the correct procedure.
Adding 10%: 200 [×] 10 [%] [+]
Subtract 10%: 200 [×] 10 [%] [-]
^Top What tests are calculators permitted for?

Press the c/ac button twice then press and hold the % button for about 3/4 seconds then press the tax+ button the current rate will come up or 0 for not set a rate. Tap in the new rate say 15 followed by % button the new rate is set. To check the rate press the c/ac button twice followed by the tax+ button hope this helps had me stumped a while

Press the CA button twice. Then push and hold down the %/set key until the 0 dissappearsd and reappears. Then type in your tax rate and the percent key (eg: 8.25%) and then press the TAX+ key. It should save the new tax rate.
