Yes. Really updated. It is one of the best. It gives hundreds of numbers, unlike other calculators. (As far as I know)

What does Σ mean?

Can you please explain it to me please?

$${\mathtt{x}} = {\mathtt{5}}$$

You can find the answer by substituting x many times. To the fifth time, the answer will equal 52 and 52. I will show you.

$$10x+2=12+8x=10*5+2=12+8*5$$

Now, multiply.

$${\mathtt{10}}{\mathtt{\,\times\,}}{\mathtt{5}} = {\mathtt{50}}$$

$${\mathtt{8}}{\mathtt{\,\times\,}}{\mathtt{5}} = {\mathtt{40}}$$

Now, you add.

$${\mathtt{50}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}} = {\mathtt{52}}$$

$${\mathtt{40}}{\mathtt{\,\small\textbf+\,}}{\mathtt{12}} = {\mathtt{52}}$$

Now, let's compare them.

$${\mathtt{52}} = {\mathtt{52}}$$

So, the equation is true.

Hope it helps!

$$20-15=5$$

5 students survived.

Try your best to know math because in life, you have to count, add subtract, and do many other things because without math, we can't survive.

Our houses are not going to be built correctly, they are going to get destroyed,...

You should evacuate the area as quick as possible. It is very important so you can survive.

And Melody, there are tornado's in the U.S.

$${\frac{{\mathtt{164}}}{{\mathtt{16}}}} = {\mathtt{10.25}}$$

So,  $${\mathtt{y}} = {\mathtt{10.25}}$$ .

Melody, the first one is REALLY EASY.

$${\frac{{\mathtt{3}}}{{\mathtt{5}}}}$$

Melody, can I do another one please?

I solved the one you told me to do.

Nice triangle Melody! I like your answer.

Can somebody explain me this problem?
