Long time viewer first time caller. I used a template created by Tim Brezezinski and was trying to modify for a little self check and teacher check as well but ran into a bit of snag. The activity is below and detailed question involving the format of a number reported out on screens 4 and 6. They are different and I don’t understand why. I like the output on screen 4 and want the same for screen 6.

I want the kids to practice writing in scientific form from standard form like on screens 3 and 4. The problem comes in screen 6 when the number reported to them is not written in standard form. The CL reports the number as 2.6e-18. Do you know how I can get it to report out like on screen 4?
In the screenshot notice that typing in 2.610^-18 has approximately equal to 2.610^-18
I adjusted your text output to show what it really is.
I think the number is too small for desmos to calculate accurately enough to say it is exactly this. Probably need to send your input3 to the graph “SciNum2” and compare to a1 for marking correct as a work around.
I added a few lines to your graph on Screen 5 and called on the math input from Screen 6.
Then on screen 6 I called on the value of E in the calculator on Screen 5. This should work. The problem is the number is there is too much variation in such small numbers between the math input and what the graph calculates.
