I like the use of PEMDAS. The use of negative/positive was not explained well enough for me to understand. please revisit this explanation. Great video. I thought (-6) - (9) = 3. In your video the answer is -15. Why
if the signs aren't the same don't you add or something? that's what i don't get like (+9)+(-7) so in front of the negative 7 there's a positive and when that happens it is automatically a positive so the answer is 2 right. But then (-8)+(-9) = -17 and in front of the -9 there is a positive so aren't you supposed to subtract? Hope you understood my question and please answer.
great explanation!

@Southaid (-6) - (9) = -15. Example: temperature is -6 degrees and then the temperature drops 9 more degrees. Now, the temperature is -15 degrees.
