My kids were talking about pemdas and I'm like... Nooo it's order of difficulty/order you are taught how to do the math. If I try to remember stuff with acronyms I spend the whole test trying to remember the acronym and if I happen to remember that I spend the whole time trying to remember what the letters stand for. That's if I actually disciplined myself to learn the acronym to start with.
"order of difficulty/order you are taught how to do the math"
Parentheses go first, obviously (you probably even learn it last since it's part of the "what order" lesson)
Exponents go second because they are the last thing you learned in math of the group (and are "hardest")
Division and multiplication are next, also next in line of learning/hardness scale
Addition and subtraction you learned first so you are going to do them last.
It's like peeling an onion, the order you learn them in is covering up the center answer so you have to peel each layer to get to the answer. You can't do addition first because multiplication and division cover that layer up.
I apparently have issues.
Does anyone else think like this??
no fives, -3 and 2 make -1 and thirty makes 29, and 40 and 18 is 58, whoops forgot 8, 58 and 16 makes 74.
The overuse of parentheses annoyed me.
I like Habba's line by line so here was mine
((5-3+(6x5)) + (8+2-5)) x 2
-3 + (6x5) + 2
-1 + (6X5)
-1 + 30
29
29 X 2
58
Done
58 + 2(8)
74
Now really done.
