So i was doing some Algebra homework and i got bored... A LOT
And i saw KrayzieTrini's question was pretty popular (And which I failed a lot at xD) so i remembered this from an old exam i had.
10*9*8*7*6*5*4*3*2*1 = 10!
^^ Can the above be true? Why or Why Not?
So, Solve it if you can. (Shame on you if you ask the internet :P)
you need to break it down:
10 x 9 = 90
90 x 8 = 720
720 x 7 = 5,040
5040 x 6 = 30,240
30240 x 5 = 151,200
151200 x 4 = 604,800
604800 x 3 = 1,814,400
1814400 x 2 = 3,628,800
3628800 x 1 = 3,628,800
So 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 3,628,800.
no order of operations is needed here because there is no other sign, only the multiplication sign. if there were brackets in there, it would be different of course
10! is equal to 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9. The exclaimation mark in mathematical terms means a factorial, which means that numbers including the number in this example '10' needs to mulitply with the other numbers below it (9,8,7,6,5,4,3,2,1), excluding zero. So i conclude that this question is true! :)
Ah yea .. lol i guess that maths isnt my strong point

Ohai google, nice to meet you!
Just because your not good with maths, doesn't mean that others aren't as well. :/
