Hi Amit, on 3.34 in your video you state that x, / and + have the same priority. I thought + is lower in precedence?

Is there an error in the video, because Amit states that + also has same precedence as x, /?

Does PEMDAS stand for Parentheses, Exponent, Multiplication, Division, Addition, and Subtraction (in that order)?

I never learned that, but it looks like it would have been helpful.

PEMDAS does stand for Parentheses, Exponent, Multiplication, Division, Addition, and Subtraction. However some of them have the same level of precedence. So it should be PE(MD)(AS) because Multiplication and Division have the same precedence level, whilst Addition and Subtraction have the same level as well, however Addition and Subtraction or lower than Multiplication and Division. If you have Multiplication and Division in the same equation, then the operator thats closest to the left has supremacy.
