Answer 1

Answer:

Standard numbers, anything greater than zero, are described as ‘positive’ numbers. We don’t put a plus sign (+) in front of them because we don’t need to since the general understanding is that numbers without a sign are positive.

Numbers that are less than zero are known as 'negative' numbers. These have a minus sign (−) in front of them to indicate that they are less than zero (for example, -10 or 'minus 10').

Answer 2

Answer:

when we go upstream then the speed of stream is being deducted from the speed of boat.

And when we go downstream then the speed of stream is being added to the speed of boat.

we can never take the negative value because speed can never be negative , it ought to be positive in every possible case.
