Not always.
Consider 4 cases 1. The sum of any two positive numbers is clearly greater than either number. 2. The sum of any two negative numbers is LESS than either of the two numbers. ( (Look at -2+(-3)=-5 .) 3. The sum of any negative number and a positive number is always greater than the negative number but less than the positive number. (Look at -2+3=1, or -5+3=-2) 4. The sum of any number and 0 is that number so it is not greater. So it appears that the sum of any two numbers is greater than either of the two numbers when the two number are both positive.
Numbers closer to zero can be either greater or lesser depending on what other numbers they are compared to.
All numbers greater than one are positive integers that are either composite or prime numbers.
Not if either of the numbers is between 0 and 1. 5*0.5 = 2.5 is not greater than 5 0.3*0.4 = 0.12 is smaller than both multiplicands.
