Just for the avoidance of confusion, the square root of 2 is 1.41 not 1.44.
To be strictly pedantic, surely ²√ 2 = ± 1.4142?
Surely basic algebra and trigonmetry is still taught at schools? I must have been about 9 or 10 when first introduced to algebra....and at the age of 12 was answering 'elementary mathematics' exam questions such as
1. Solve 3(2x+7)² - 4(2x+7) - 15 = 0
2. A reservoir has an area of 6.6 acres and has an average depth of 8 ft. Calculate the number of gallons of water in the reservoir when it is full. If all the water can be put into a tank shaped like a cube, how long is one side of the cube?
Trig came a little later, but at 14 we were taught basic calculus.
The current 'maths isn't necessary' nonsense is driven by those too stupid to bother to study anything which requires effort and discipline.
