Andre and Diego each square a different number and get the same answer (4). Jada and Elena each square a different number and get the same answer (-4). Is there any way to code it so that Andre and Diego can have either -2 and 2 (doesn’t matter who has which) but that if Diego has one solution the…

Thank you! I’m wondering how the coding would look on the second part (highlighted in blue) if the inputs are not numeric values but latex (we are working with complex numbers, so the correct answers would be 2i and -2i.) correct = (this.latex = -2i or this.latex = 2i) and not(numericValue("\abs({i…

Try using a simpleFunction instead of numericValue and treat i as a variable. Like this (with something similar in input3) value=simpleFunction(this.latex,"i").evaluateAt(1) check= (value=-2 or value=2) and not(this.numericValue=2 or this.numericValue=-2) and not(numericValue("\abs(${input3.scrip…

Thank you for your help! I think it’s working now. I had to take out this line: and not(this.numericValue=2 or this.numericValue=-2) otherwise, it checked the second answer wrong every time, but when I took that out, it seemed to work just like I was hoping it would. Thanks!

Thought I had this, but everything is working but the last response. I have a feeling it has something to do with the coding in input6 referring back to input5 but I’m not having any luck in figuring it out. If anyone would be able to take a look and help me with the way it should be coded, I woul…

This should work for your check on input6 and it’s consistent with how you checked input5. check= (this.latex = `2i` or this.latex = `-2i`) and not(this.latex=input5.latex)

Thank you! This works like a dream!
