@benny.math: x = 10³ + 20³ + 30³ I used to do that too. But there's a super easy way to do it in your head. Just cube each one. 10 × 10 × 10 is 1000. 20 × 20 × 20 is 8000. And 30 × 30 × 30 is 27000. Add them together and you get 36000. Done. And here's the part I love. Look at the numbers again: 1, 8 and 27. Those are just 1³, 2³ and 3³ with three zeros tacked on the end. So you can do 1 + 8 + 27 = 36, slap the zeros back on, and boom, 36000 ✨ Try it yourself with 40³ + 50³ and drop your answer in the comments. I'll see who gets it first 👀 Save this one for later and follow for more quick math tricks! #math #maths #algebra #mathematics #mathtrick
