The P.I.E Chart Power(Watts) = I(Amps * E(Volts)
Choose numbers in place of the letters
Like 10 For (P) 5 For (I) 2 For (E)
Keep the same chosen number for each letter
Say P=10 I=5 E=2
P(10) = I(5) * E(2)
I(5)= P(10) / E(2)
E(2) = P(10) / I(5)
-----------------------------------------
E=M*C2
(E) Is 6 = (M) Is 3 * (C2) Is 2
E(6) = M(3) * C(22)
M(3) = E(6) / C(22)
C(22) = E(6) / M(3)
Parentheses, Exponents, Multiply, Divide, Add, Subtract
Never do Math Only by Left to Right
Follow the Rules P,E,M,D,A,S or P,E,D,M,S,A
Always do * or ÷ First then do + or -
------------------------------------------
2+4-3*4÷2=6 Wrong: See it as
(2+4)-(3*4÷2)=0 Correct
6-6=0
------------------------------------------
Try to group * ÷ signs together
6-3*32+4÷2=15.5 Wrong
6-(3*32)+(4÷2)=-19 Correct
Left to Right after All () Exponents * or ÷
6-27+2=-19
------------------------------------------
Parentheses first also ÷ or * first inside ()
7-2*(3+4-1*4÷2)=36 Wrong
work inside () first & * or ÷ First
1*4÷2=2 now 3+4-2=5 is the Total inside ()
7-2*(5)=25 Wrong 7-(2*5)=-3 0r 7-10=-3
Get X alone using *, /, +,- Equally to each side
5X-4=11 remove -4 by adding 4 to each side
5X-4+4=11+4 gives 5X=15 now let's / both sides by 5
5X/5=15/5 give the answer to X which is X=3
------------------------------------------
A little harder variables on both sides
3X-7=9X+17 subtract both sides by 3X
3X-3X-7=9X-3X+17 give -7=6X+17
get X on one side by subtracting 17 on each side
-7-17=6X+17-17 gives -24=6X divide both sides by 6
-24/6=6X/6 gives the answer -4=X
------------------------------------------
5-2(3X+1)=7(2X+5)-8 Rules () first
5-2*3X & -2*1 also 7*2x & 7*5-8 gives
5-6X-2=14X+35-8 Notice only + & - now
5-2-6X=35-8+14X gives 3-6X=27+14X
keep going by adding 6X to both sides
3-6X+6x=27+14X+6X gives 3=27+20X
get X on one side by subtracting 27 on both sides
3-27=27-27+20X gives -24=20X divide both side by 20
-24/20=20X/20 fraction 4 into -24=-6 4 into 20=5
Answer X=-6/5 or X=-1.2
------------------------------------------
Don't get confused by Fractions
⅔X=8 just multiply both sides by 3
⅔X*3=8*3 gives 2X=24 divide both sides by 2
2X/2=24/2 Answer X=12
