Numbers & the Math Object

The video tutorial covers basic math operations using JavaScript, including addition, subtraction, multiplication, division, and modulus. It introduces the Math object and its properties, such as Pi and Euler's number, and demonstrates various Math methods like rounding, power, min/max, and generating random numbers. The tutorial concludes with a preview of the next video, which will focus on string manipulation.
