What's 13 x 17?
>>
21+70+30+100=221
>>
>>12372240
Correct
>>
13*17
=130*170/100
=22100/100
=tan^2(x)cos^2(x)*22100/100sin^2(x)
=221
>>
(10 + 3) * 17 = 170 + 3*(17) = 170 + 3 * (10 + 7) = 170 + 30 + 3 * 7 = 200 + 21 = 221

a lot.

>>12372235
170+30+21
>>
15^2 - 4
>>
>>12372235
13 and 17 arent real
>>
15^2 - 2^2
or
100(1)+10(7+3)+1(7×3) = 2(10^2)+7*3
>>
>>12372444
>>
>>12372235
$13 \cdot 17 = (15-2)(15+2) = 15^2-2^2=225-4=221$
>>
10*10+(3+7)*10+3*7
>>
yes i did that in my brain, faggots
>>
>>12372235
13+7 = 20
20x10 = 200
3*7 = 21
200+21 = 221
>>
