The sum of two rational numbers is rational.From there, it follows that the sum of a finite set of rational numbers is also rational.
This sum is zero, neutral.
No. In fact the sum of a rational and an irrational MUST be irrational.
Yes.
They are always rational.
Algebraic expressions are useful for translating problems into the language of mathematics. An algebraic expression for the problem "6 times the sum of 4 and y" would be: 6(4+y) = 24 + 6y.
Sum of fifteen minus b
Such a sum is always rational.
The sum of two rational numbers is rational.From there, it follows that the sum of a finite set of rational numbers is also rational.
The sum of any finite set of rational numbers is a rational number.
The magnitude of the vector sum will only equal the magnitude of algebraic sum, when the vectors are pointing in the same direction.
No - the sum of any two rational numbers is still rational:
You may be referring the the word sum, which is the addition of a set of numbers
This sum is zero, neutral.
No. In fact the sum of a rational and an irrational MUST be irrational.
Yes.
They are always rational.
