Mathematics is a magical subject, and its charm lies not only in its wide application, but also in its infinite mystery. Through mathematics, we can solve many seemingly complicated problems.
Calculation method of isosceles right angle
Through simple calculation, we can easily calculate the angle of isosceles right angle. For example:10.180 * 2/(2+1+1) = 90 degrees, then an isosceles right angle can be simply calculated.
Calculation method of circular area
The area of a circle is a very basic mathematical problem, but we can easily calculate the area of a circle through a simple formula. For example: 12.56 * 2/3. 14/2 = 4 (cm), then 3.14 * 4 = 50.24 (cm 2).
Challenge the limits of the brain
Mathematical magic is a good challenge. It can exercise our brains and improve our thinking ability. Come and try it, use your brains to solve these mathematical magic and feel the charm of mathematics!
