I was going to comment, but changed my mind, but then when I saw this:by pylkko » p.s imagine if you had not memorized the times tables in primary school. You'd be looking up 6 x 8 on google
And decided to go ahead, there really are quite a few people that do notby pendrachken » I'm in my late 30's and never memorized the times table.
know even the basic times tables, 1 thru 10,...for what ever reasons.
I think it is important, but in these days with calculators, maybe it isn't.
Any way here is something to help people memorize them, if they want to.
Often I do have to do a search, example " What is the Linux command to "do this or that task" ? (where is says "this or that task" , would be a description of the task in question),.... another example, a new user might have to ask
"what is the linux command to list directories ? " or
"what is the linux command to multiply " ?
You can use 'bc' to do math, including multiply,
Code: Select all
man bc
For example:BC(1) General Commands Manual BC(1)
NAME
bc - arbitrary-precision arithmetic language and calculator
SYNOPSIS
bc [-cl] [-e expression] [file ...]
DESCRIPTION
bc is an interactive processor for a language which resembles C but
provides unlimited precision arithmetic. It takes input from any
expressions on the command line and any files given, then reads the
standard input.
Code: Select all
$ bc
573 * 4
2292
2292 * 5789
13268388
13268388 / 5789
2292
quit
to remember the commands they use the most, some people would have to
do a search to find the right command for a task more often then others, it all
depends on their memory and how many commands they are all ready familiar
with, ......Now that I understand the question better............
