Hello World! $\frac{\sqrt{x + y}}{4}$ is today's lesson

the $\sqrt{x + y}$ is first

Start with $\frac{\frac{x+1}{x+2}}{x+3}$ then we get $ 2+x $ and $3$.

There are three formulas to know:

the first is $\gamma^2 + \theta^2 = \omega^2$

$\sqrt{x^2+1}$ is next

Integral $\int_{a}^{b} x^2 ,dx$ is last

Start typing below to see the output.

I spent $5 at the grocery store. Then I bought a $2.50 ice cream cone.
