I used to not have problems with this, but summer happened.
I know the solutions, I just don't understand what i'm doing wrong.
Heres what I did:
-5+1*3-(7-23)
-5+1*3-(7-8)
-5+1*3-(-1)
-5+3-(-1)
-2-(1)
-3
(Actual solution is -1)
Next Problem:
(8-2)2+1/4[4-3(6-10)]
6^2+0.25[1(-4)]
36+0.25(-4)
36+(-1)
35
(Actual solution is 40)
Notice in the first one, Thehumancalculator that :
-5+3-(-1) =
-5 + 3 + 1 =
-5 + 4 =
-1
Next one ;
(8-2)2+1/4[4-3(6-10)] =
6^2 + (1/4)[ 4 - 3(-4)] =
6^2 + (1/4)[4 + 12]
6^2 + (1/4)[16] =
6^2 + 4 =
36 + 4 =
40
[Hey......I know all about that Summer thing....it used to happen to me, too !!...LOL!!!]
remember PEMDAS
paraenthesis
exponents
multiplication
division
addition
subtraction
