Why the order of operations matter!By Ella Acheson 7th grade math
Block: H
Order of operations
0 Order of operations are exactly what it sounds like, it tells you what order to do math equations in.
0 They are important because to do a complicated equation, with more than one operation in it, you need to know the order because other wise you could get a completely different answer.
0 In order operations you have to do numbers/equations in brackets and exponents first.
0 Secondly you would do the multiplication or division equations first
0 And lastly you would work out addition or subtraction
Examples
03(4+5) − 2 squared = 23
4 (1st) 9 (2nd) 3x9= 27 (3rd) 27 – 4 = 23 (4th)04+6x(5-2) = 30 0 (9+10) x (5+7)= 228
