The rule simply dictates that brackets must be first opened to unfold the calculation after which must be performed any of the two higher operations before any of the two lower operations. It is a convention agreed by mathematicians so that they work things out in the same way and therefore get the same answers hopefully. The PEMDAS rule can be remembered using the acronym Please Excuse My Dear Aunt Sally.
I am really getting confuse with these two or three order of operations I already know the differences between PB which is bracket and perentheses and O and E as O stands for Order Exponents and Exponents but why do they have to change it to BODMAS when its the same thing as BEDMASs meaning.
Reverse the order of multiplication vs division. Difference between BEDMASBODMAS and PEMDAS. BODMAS is an acronym or mnemonic used to help pupils remember the correct order to complete mathematical calculations in this called order of operations. I am really getting confuse with these two or three order of operations I already know the differences between PB which is bracket and perentheses and O and E as O stands for Order Exponents and Exponents but why do they have to change it to BODMAS when its the same thing as BEDMASs meaning.
