I’ve just signed up for vyew; am able to cause it to operate as documented.
Am, short-term, intending to use for specific purpose of tutoring mathematics; especially Algebra.
“Would be nice” if it had a function to, given an equation such as:
x + 3 = 5
accept “any operation” against both sides. Such as:
add +3; giving x + 6 = 8, or
add -3; giving x = 2
Intent being that student could try both of these; see which one(s) got the job done. (Real-world equations/operations would be considerably more complex . . )
