School Math vs University Math 🤯🤯

It's a 3 4 5 triangle so it's 20, no calculations needed.

Observe that 15 and 25 are multiples of 5 and make two sides of a 3,4,5 right angled triangle so the remaining side is 4x5=20

Or you could just understand it’s a 3 4 5 triangle scaled up. Becomes pretty simple after that.

No. Univertsity math is to see 3:4:5 triangle. One step 20

This is typical math-bullshit that works only in some combinations. Doesn't work vor 3 instead of 15 and 5 instead of 25 (result should be 4).

3-4-5. No pen needed. 3 sides are 15-20-25

Ph.D. math: 15=5x3 25=5x5 Solve for a smaller triangle with side=3 and hypotenuse=5. The other side is therefore=4. Multiply by 5. The answer is 20. All in your head. 3 seconds.

has nothing to do with university. It's simple Pythagorean theorem and difference of squares

İt is big lie. Now prove that 3,4,5 Pisagor with same way! 3+5=4????

Bro in college side you only applied a2-b2=(a+b)*(a-b)

3 4 5 triangle stop complicating it

Wait, they don't teach basic algebra in schools anymore?

ne uzattın amk 3 4 5 kuralı diye bağırıyor soru😁

School math feels like memorizing formulas, while uni math’s all about *why* they work. So yeah, college math is basically just high school with

He basically did the same thing in two different ways. Both are school math. Now solve tensor algebra

Suppose Pythagoras had died of diarrhea as a child, and no one else had ever discovered his theorem; Then we would have to solve this problem the following way... As a side note: In universities, usually professors tend to emphasize on std methods over quick shortcuts or tricks.

Or you could just accept it’s a 3,4,5 triangle!

Here university maths was more like this: "Let's assume x=20. Now let's proof it. yada yada ya. trivial. lets skip one or two steps and then we have it. q.e.d" Me:😵‍💫

lol.. it’s just difference of two squares.

The university relies on difference of two square formula

İkiside yanlış 3,4,5 üçgeninden hesap yapmadan 20

At my school I learned to recognise 3-4-5 triangles

وأنا أشرحها لك بالطريقة السعودية 1-إذا مقابل الزاوية 90 غير معلوم قم بتربيع الضلعين ثم اجمعهم ثم اجذرهم 2- إذا ضلع غير مقابل 90 مجهول ربع الضلعين وقم بطرحهم ثم جذرهم هذي طريقتي السعودية وأتحدى فيثاغورس أو أي جامعة أسرع من هذه الطريقة

Or just do it in your head in a few seconds.

a2-b2= (a- b)(a+b)
