Decimal Number System-is a number system that has a base of 10 and a symbol of 10 ( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10).In adding of a number using this system, add then use a carry over on the tens digit.In subtracting of a number using this system, subtract if possible but if not, borrow 1 from the other digit then add 10 to the digit. It is the most commonly use among all number system.Ex.42310 1st digit: 3+4=7 452101st digit: 2+10-3=9 +45410 2nd digit: 2+5=7 -24310 2nd digit:5-1-4=0 87710 3rd digit: 4+4=8 209103rd digit:4-2=2
Binary Number System-is a number system that has a base of 2 and a symbol of 2 ( 0, 1,).In adding of a number using this system, add then use a carry over on the tens digit.In subtracting of a number using this system, subtract if possible but if not, borrow 1 from the other digit then add 2 to the digit. Ex. 1012 1st digit:1+0=1 1012 1st digit:1-1=0 +102 2nd digit:0+1=1 -112 2nd digit:0+2-1=1 1112 3rd digit:1 102 3rd digit:1-1=0
Octal Number System-is a number system that has a base of 8 and a symbol of 8 ( 0, 1, 2, 3, 4, 5, 6, 7,8).In adding of a number using this system, add then use a carry over on the tens digit.In subtracting of a number using this system, subtract if possible but if not, borrow 1 from the other digit then add 8 to the digit. Ex. 778 1st digit:7+0=7 7012 1st digit:1-1=0 +108 2nd digit:7+1=8-8=0 -612 2nd digit:0+8-6=2 1078 3rd digit:1 6102 3rd digit:7-1=6
Octal Number System-is a number system that has a base of 16 and a symbol of 16 ( 0, 1, 2, 3, 4, 5, 6, 7, 8 ,9, A, B, C, D, E).A indicates 10 as in B indicates 11 and respectively.In adding of a number using this system, add then use a carry over on the tens digit.In subtracting of a number using this system, subtract if possible but if not, borrow 1 from the other digit then add 16 to the digit.Ex. 2A16 1st digit:10+0=10 7A12 1st digit:1-1=0 +B016 2nd digit:2+11=13 - 612 2nd digit:10-6=4 DA16 7402 3rd digit:7
