Vedic maths is a collection of sixteen sutras — shortcut rules — popularised in India in the twentieth century. Some of them are genuinely faster than the standard written method, and the two most useful are here: multiplying by eleven, and squaring any number ending in five.
Multiplying by eleven: write the outer digits, and put their sum in the middle. 32 × 11 becomes 3, then 3+2, then 2 — 352. Squaring a number ending in five: multiply the leading part by the next number up, then stick 25 on the end. 35² becomes 3×4 = 12, then 25 — 1225.
Each round shows the rule again if you get it wrong, so you can learn the method by playing rather than by memorising it first.

Real mathematics. Every sutra here is an ordinary algebraic identity written as a procedure — squaring numbers ending in five works because (10a+5)² = 100a(a+1) + 25.
At the specific patterns, yes, dramatically. Multiplying by eleven becomes instant. The broader claim that Vedic maths makes you faster at all arithmetic is overstated, and worth being honest about.
Not at all. The methods work whether or not you can name them.
