    numbers are important because without them,we won't have anything to represent quantities and without quantities,we can't make calculations...an without calculations mankind would not have progress in life, yet again survive...think about it...numbers play a huge part in our life...for starters....think about when the cave men had to hunt 4 food...think about how numbers apply there...

    How will the world be if it had no fractions?

    is that the same as not having any numbers? because a whole number like 5...can be represented by 5/5....

    If the world had no negative numbers we would not be able to calculate an object when falling or descending,we would be able to calculate the distance moving left or south(backwards), we would not be able to calculate speed when reversing and temperature when it is getting colder.

    A number is a numerical value which can be used to determine the amount of an object, for what ever purpose, We use numbers in everyday life weather we realise it or not, if it is to count money to our age.

    Numbers are important for calculations to find how much apples there are on a tree or in a barrel.
