> 4 quadrillion (4×10¹⁸) + 70 trillion (7×10¹³)

That's 4 quintillion.

Thank you, I have just fixed it.

You also need to fix this sentence:

"i aim to push this farther to 5 quadrillion."

Thank you, I have just fixed it. This is so helpful, thank you from the bottom of my heart.

Keep doing stuff you like.
