    47 * 8 = 376 so 4.7 * 8 = 37.6

    37.6 + 3.29 = 40.89

    If you can remember two numbers for 5 secs it's not difficult.

    Yes but like do you have any intermediary steps for 4.7 * 8 or does it just being in your head like 2+2? I'm pretty sure simple stuff like 2+2 etc I volved recall more than logical processing in the brain.

    I forgot the .7 in 8.7, which is what complicates things a bit.

    I can multiply 3 digit numbers in my head in a way I can put into words.
