ScarPion, afsuski yo'. Toq soni toq matta qo'shsa toq chiqadi. Toq soni juft matta qo'shsa juft chiqadi. Bu isbotlangan. Kak 2x2=5 digani kak

uZaFaRaP, chiqadi
4=5 shunga ishonasmi yani 4 sonini 5 ga teng ekanini isbotlab beraman

ScarPion, 4+5=5+4

4-4=5-5
4(1-1)=5(1-1) bu yerda (1-1) qisqaradi
4=5 wunaqami
