Exponent then M/D then A/S by Ryan Peterson https://padlet.com/rpeterson8/sbrvsz33dkgv Made with charm en-us 2017-03-13 17:04:56 UTC 2017-03-13 19:06:36 UTC hello@padlet.com The basic principle: "more powerful" operations have priority over "less powerful" ones. rpeterson8 https://padlet.com/rpeterson8/sbrvsz33dkgv/wish/159755282

Using a number as an exponent (e.g., 58 = 390625) has, in general, the "most powerful" effect; using the same number as a multiplier (e.g., 5 x 8 = 40) has a weaker effect; addition has, in general, the "weakest" effect (e.g., 5 + 8 = 13). Although these terms (powerful, weak) are not used in mathematics, the sense is preserved in the language of "raising 5 to the 8th power." Exponentiation is "powerful" and so it comes first! Addition/subtraction are "weak," so they come last. Multiplication/division come in between.

You do this by taking apart the most complicated, highest, parts first (driving into the parenthesis and other groupings and evaluating them first, bringing back a number to combine with other numbers); then the middle parts (exponents being repeated multiplication, then multiplication being repeated addition) are dismantled, and finally the parts you've found are added or subtracted.
