“ The essence of mathematics is not to make simple things complicated but to make complicated things simple” - S.Gudder]]> 2020-08-03 01:11:49 UTC https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/667616923 How was the number system invented? mypsubscriptions1 https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679869941 2020-08-14 04:03:52 UTC https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679869941 Jonathan jonathanc14 https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679904900 The number system began with just tally marks.]]> 2020-08-14 04:48:53 UTC https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679904900 Fayza fayza1 https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679907807 The majority of ancient math systems started out with tally marks.]]> 2020-08-14 04:53:10 UTC https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679907807 Rachel rachelm44 https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679971439 Number systems started off with counting of fingers until it was developed into sign language then to carving tallies on wood or bones. ]]> 2020-08-14 06:33:39 UTC https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679971439 Min Ah minah2 https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679973568 The first number system were tally marks which was made on sticks.]]> 2020-08-14 06:36:32 UTC https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679973568 Leon Leon99900 https://padlet.com/mypsubscriptions1/81giaxiiyvp4e7py/wish/679992508 The number system started with tally marks.

2.Rational numbers are numbers that can be expressed in the form of a ratio 

Irrational numbers are numbers that can not be expressed as a fraction. 
3.√5 is irrational because it cannot be expressed as a fraction

  • Rational numbers are types of real numbers that can be expressed into a fraction, decimal, ratio or integer. Irrational numbers are types of numbers that cannot be expressed in a simple way.
  • Rational numbers are numbers that are simplified and can be expressed easily in a form of a fraction or ratio while irrational numbers are complicated and cannot be easily written.
  • The square root of five is considered irrational because if you simplify it to a decimal form, it becomes too difficult to express into fraction. In this case, the answer would be a non-terminating decimal.

  • The value of negative 25 square rooted is undefined
  • We can’t square root a negative number because all negative numbers need to be multiplied by the same number but with different signs such as -5 x 5.
