......!!!!!!!!...................................
RESPONSE --> It would be a positive because a negative * negative will equal a positive. confidence assessment: 2
.................................................
......!!!!!!!!...................................
16:15:39 ** The square root of a negative will often give you an error (what can you square to get a negative, since any number squared is positive?), but on certain calculators it gives a complex number (actually two complex numbers). These are not real numbers; for the purposes of this course there is no real square root of a negative number. There is no real number that can be squared to give a negative. If you square a negative number you get a negative times a negative, which is positive. If you square a positive number you get a positive number. So a negative number has no real square root. **

RESPONSE --> It is correct that negative * negative = positive but I also see that a negative does not have a real square root. self critique assessment: 2

16:20:16 Query 1.4.42 drawer has 18 compartments; how many drawers to hold 204 tapes?
......!!!!!!!!...................................
RESPONSE --> 204/18=11 with 6 leftover. So we need 12 drawers all together. confidence assessment: 1
.................................................
......!!!!!!!!...................................
16:20:30 ** 204 / 18 = 11 with remainder 6. If we had 11 drawers they would hold all but 6 of the tapes. The leftover tapes also have to go into a drawer, so we need a 12th drawer. **
