How do you factorise 169 - t squared?
I think the answer is (13-t)(13+t) because when you expand the brackets some of it cancells out like +169 - 169. As they are the same (but ones got a plus and ones got a minus) they cancel each other out. :)
Why is a negative exponent minus a positive exponent a negative exponent?
when you're doing a problem like that use this trick. let's say you have 3 to the -7 power minus 3 to the 4 power. -7 - 4 can also be shown as -7 + -4. i switched the minus sign to a plus sign and because i did that, i had to switch the positive 4 to a negative 4. so i got 3 to the -7 power plus 3 to the -4 power.
Why does minus minus a minus equal a minus?
Minus minus a minus does not necessarily produce a minus answer.Here is an example of a minus figure, minus another minus figure:-3 - (-5) = -3 + 5 = +2As long as the absolute value of the first number is smaller than that of the second, the final answer will always be positive.If the two are equal, the final answer is 0:-4 - (-4) = -4 + 4 = 0Only if the magnitude of the first is larger than the second is the answer negative: -3 - (-2) = -3 + 2 = -1-------------------------------------------------------------------------------------------------------HOWEVER, if we are trying to determine the sign of a number that has multiple signs, for example (-3), -(-3), or -(-(-3)), [minus, minus a minus] then the logic is this:A negative is a negative, so -3 is negative, and means deduct 3A negative negative is a positive, so -(-3) is positive and means add 3A negative 'negative negative' is a negative, so -(-(-3)) [i.e. minus, minus a minus] is negative and means minus 3Let's work it through another way:If minus n means minus nThen minus (minus n) must mean plus nTherefore minus (minus (minus n)) must mean minus nYet another way to think of it:If you add a minus figure to a calculation, you deduct it.But if you deduct a minus figure, you must ADD it (thereby reversing its original 'negativity' and the figure become a positive one)So if you have to then 'minus' it once more, (thereby reversing its positive status) it has 'minus' value again.Method of determining the signIf you have a formula with 'stacked' minuses, remove them in pairs, starting from the left. If you've got one left, the resulting value will be a minus figure. But if 'pairing' them removes them all, then the remaining figure is positive, i.e. '+'.

+/- is strictly based on the players on the ice at the time of the goal. Yes, sometimes players are lucky/unlucky in the way they may receive a plus or minus since they just got on the ice and had little involvement in the play.
