This math problem went viral after being posted in 2020.
Celeste Ng tweeted 'At dinner, nine year old made up a math problem and made his father and me solve it. Our attempt at simultaneous equations got really complicated. We figured it out via guess and check, but I still think there has to be a more elegant way.'
Can you solve the nine year old math problem using both guess and check and the elegant way - using algebra?

Ratios are said to be in proportion if they equal. This video looks at how to simply see if two ratios are in proportion - that is whether they are equivalent. We then look at how to easily find out how much of a quantity is required to keep something in proportion. To support free math on Patreon (thank you): https://www.patreon.com/tecmath

This amazing math trick can be used to multiply two digit numbers instantly.
It is important to remember that for this particular multiplcation trick that it is just that - it is very specific and has a few conditions which must be met in order for it to work. First the first numbers must add up to ten, and secondly the last numbers must be the same....so very limited, but cool nonetheless!

In this lesson, you will learn to multiply fractions quickly and easily.
To multiply fractions you multiply across the numerators (the top number of a fraction) and multiply across the denominators (the bottom number).

An example I always use to start this off is multiply 1/2 with a 1/2. The numerators multiply to give 1 (1 x1), the denominators multiply to give 4 (2x2). Hence a 1/2 multiplied by a 1/2 is 1/4.

What about if you multiply 2/3x1/4?
Top number (2x1), bottom number (3x4).
So 2/3x1/4 = 2/12. To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU

This looks at how to do simple addition in maths.
No tricks, no fuss.
This is one of the most basic things in maths - yet as a senior level maths teacher I am astounded how many people lack this ability - and as such they struggle throughout their school years at maths.
Addition, subtraction, division and multiplication - these are the most important thing anyone should know in maths , yet a large number of people who still are yet to attain this skill!
