Also known as order of operations

Or something like that

You said it was 5171?

Double is adding 100%

At a rate of 5%,  it will take 20 years because 5*20=100

$${{\mathtt{2}}}^{{\mathtt{3}}}{\mathtt{\,\times\,}}{{\mathtt{7}}}^{{\mathtt{1}}}{\mathtt{\,-\,}}{{\mathtt{6}}}^{{\mathtt{2}}} = {\mathtt{20}}$$

Uh-oh.....I don't have any work!

Uh-oh......Showing my work is my enemy.......(Melody!  I don't know what the phrase "show your work" means!  LOL!)

Actually,  x is greater than 7....where'd you get your answer, Z?

That's my way too!  Good job Alexa!

IDK...............................

Well 2*7-4=10

So x is <7
