What is 111,111,111 x 111,111,111 ? Or to put it another way, can you do mathematics without the internet ????
12,345,678,987,654,321, at least that's what I get without writing anything. I may have missed something, but if you write nine 1s and then add ten times that number, ten times the result, and repeat that 7 more times that's the result.
That's looks about right ?
I don’t have a numerical brain, can’t even remember phone numbers that I use regularly.
I am ashamed to say I don't do maths. I missed out a few months of schooling in my early teens and couldn't catch up the maths. I am sure with application I could get back but it just addled my brain. ?
