Easy & Brilliant Math Tricks 🔢

" Arithmetic or maths problems aren't about how you solve them. It's the meaning behind the problem that is important."

Only mechanical learning! No meaning at all! It’s not brilliant!

@factoryfootages When you square a number ending in 5, the answer ends in 25. The front part is x times x+1, where x is the first number (7*8 using the example in the video).

🧠👍

Impressive, but I have known this trick 75x75 = (7x(7+7),5*5 = 7*8,5*5 = 56,25 = 5625, a bit faster. It works for anything followed by 5. e.g. 125X125 = 12x13,25 = 144+12,25 = 15625~!
