Presumably you mean is it true that: ( A nor B ) nor C == A nor ( B nor C ) ? No. Let's make a table: A B C (A nor B) (B nor C) [ (A nor B ) nor C ] [ A nor ( B nor C ) ] 0 0 0 1 1 0 0 0 0 1 1 0 0 1 .... So you see right away for A=0, B=0, and C=1 it doesn't work.
a= (+a) or a= (-) b= 2a b= 2a c= (-a) c= (+a)
#include<stdio.h> #include<conio.h> void main() { int a,b,c; clrscr(); printf("Enter any three numbers"); scanf("%d%d%d",&a,&b,&c); if(a>b&&a>c) printf("A is greatest"); else if(b>a&&a>c) printf("B is greatest"); else if(c>a&&c>b) printf("C is greatest"); if(a<b&&a<c) printf("A is smallest"); else if(b<a&&b<c) printf("B is smallest"); else if(c<a&&c<b) printf("C is smallest"); getch(); }
You haven't provided any choices for the "which of the following" part of your question. Such questions are best avoided here. However, assuming a, b and c are all natural numbers, all of the following are true for a<b AND b+c=10: a=1, b=2, c=8 a=1, b=3, c=7 a=1, b=4, c=6 a=1, b=5, c=5 a=1, b=6, c=4 a=1, b=7, c=3 a=1, b=8, c=2 a=1, b=9, c=1 a=2, b=3, c=7 a=2, b=4, c=6 a=2, b=5, c=5 a=2, b=6, c=4 a=2, b=7, c=3 a=2, b=8, c=2 a=2, b=9, c=1 a=3, b=4, c=6 a=3, b=5, c=5 a=3, b=6, c=4 a=3, b=7, c=3 a=3, b=8, c=2 a=3, b=9, c=1 a=4, b=5, c=5 a=4, b=6, c=4 a=4, b=7, c=3 a=4, b=8, c=2 a=4, b=9, c=1 a=5, b=6, c=4 a=5, b=7, c=3 a=5, b=8, c=2 a=5, b=9, c=1 a=6, b=7, c=3 a=6, b=8, c=2 a=6, b=9, c=1 a=7, b=8, c=2 a=7, b=9, c=1 a=8, b=9, c=1

It means a*b = c
Oh, and I mean A+B+C=BB
for example if a=b+c and c>0, then a>b
b divided by 2
The distributive property states that a × (b + c) = a × b + a × c
The answer depends on whether you mean A intersecting (B union C) or (A intersecting B) union C.
back
b=2 a=1 c=3 so b plus a =c
The associative property states that the result of an addition or multiplication sentence will be the same no matter the grouping of the terms. Associative: (a + b) + c = a + (b + c) (a × b) × c = a × (b × c)
A,b,c are variables. They usually refer to the sides of a triangle, but also can mean just normal variables.
p=a+b+c for a
the answer is that a plus c is equal to b.
