Using Engineering Symbols; Prime Factorization; Calculation History And Replay - Casio fx-570AR X User Manual

Note: The calculation result shown above is what appears when Off is
selected for the Engineer Symbol setting on the setup menu.

Using Engineering Symbols

Your calculator supports the use of 11 engineering symbols (m, μ, n, p, f, k,
M, G, T, P, E) that you can use for input of value or for calculation result
display.
To display calculation results with engineering symbols
On the setup menu, change the Engineer Symbol setting to On.
Example Input and Calculations Using Engineering Symbols
To input 500k
To calculate 999k (kilo) + 25k (kilo) = 1.024M (Mega) = 1024k (kilo) =
1024000

Prime Factorization

factored to prime factors.
To perform prime factorization on 1014
To re-display the unfactored value, press (FACT) or .
Note: The types of values described below cannot be factored, even if they
have 10 or fewer digits.
• One of the prime factors of the value is 1018081 or greater.
• Two or more of the prime factors of the value have more than three digits.
The part that cannot be factored will be enclosed in parentheses on the
display.

Calculation History and Replay

Calculation History
An  and/or  at the top of the display indicates that there is more

calculation history contents using  and .
2 + 2 = 4
3 + 3 = 6
Note: Calculation history data is all cleared whenever you press , when
you change to a different calculation mode, when you change the Input/
Output setting, or whenever you perform a RESET operation ("Initialize All"
or "Setup Data").
