Identyfying , Testing and combining Reseators

The first two or thre colour bands have valve we can write the number.
The third or next number is the multiplier numbers (how many zero can add to the number).
The 3rd band also has two new colours where Gold=.1 and selver  = .01
The last band is the resistor tolerance valve Gold = 5% and Selver = 10 % and no band whatever = 20%

Ihave choosed 6 resistors diffrent colours bands including tolarance vaalve below chart i have record the valve of colours code and valve of multimeter.

Colour of bands	Valve (colour cods)	Valve (multimeter)
Green,violet,grey,gold	570000000+-5%	5.68 M ohms
Brown, black, orange, gold	10000+-5%	10 K ohms
Brown, black, red, gold	1000+-5%	1 K ohms
Red, violet, green, gold	2700000+-5%	2.7 M ohms
Orange, orange, black, gold	330+-5%	33 ohms
Red, red,green, gold	2200000+-5%	2.190M ohms

I have  Choose two resistors and recorded their individual ohm resistance value measured with a multimeter:
resistor 1: 1.93 ohms                Resistor 2: 33 ohms
I have put these resistors together in series and then calculated and measured their
calculated value 1 and 2 in series: RT= R1+R2 (R1:993 ohms + R2: 33 ohms = RT 1026 ohms
measured value 1 and 2 in series: 1.26 K ohms

And then i put these two resistors together in parallel
Calculated value 1 and 2 in parallel
RT = (R1 x R2/R1+R2)  993 x 33 = 32769/1026 = 31.93 ohms

What principles of electricity have you demonstrated with this? explain.
In series circuit the total resistance equal to resistor 1 and resistor 2 (RT = R1+R2+R3) . In this experiment i have put two resistors in series and the resistance for both were equal.
If two resistors are connected in parallel the total resistance can be found using the formula RT = (R1 x R2/R1+R2)
The total resistance in parallel circuit must be less than the smallest resistance in the circuit.
