In the 16th century GirolamoCardanon, a famous Italian mathematician and physician, for the first time described negative numbers as fictitious and accepted the possibility of them being the solutions to equations.

He described this in his famous book ‘ArsMagnia’ which was published in 1545.

### Rules that exist for performing operations with integers

Different signs, subtract

Take the sign of the bigger absolute value

Then you will be exact !

Multiplication and division rules

SPON works !

S = same signs P = positive

O = opposite signs N = negative

Same signs positive , opposite signs negative

### Integers in sports

• Integers are used in many indoor and outdoor games.

Here is an example:

Gita is leading by 8 points.

The board game is coming to an end.

Gita answers it correctly and she gets +1!

While Gita is taking a break, the score keeper catches Rohit cheating.

Rohit gets -1.

In hockey,

Team Fireball scores a goal!

They get +1so Team Dragon gets -1.

Now Team Fireball gets -1 as Team Dragon scores a goal +1.

### Integers in weather and distance

• Weather

when the temperature is above 0,it is represented by + sign.

when the temperature is below 0,it is represented by – sign.

### Directed numbers

Many of the numbers we use represent situations which have directions.

These numbers are called directed numbers.

Once a number is chosen as positive(+), the opposite is chosen as negative(-).

Directed numbers are used in Mathematics, engineering, business , and sciences.

If a directed number is a whole number , it is called an integer.

•  If 40km due East = +40

40km due west = -40

30m above sea level= +30

30m below sea level= -30

29m due North= +29

29m due south= -29

### Budgeting

If the budget exceeds a certain amount then it is negative(-).

If costs are within the budget, then it is positive(+).

### For example:

• Katy’s parents have given her a budget of Rs. 50.

• Katy happily picks many dresses .While she is at the counter she realizes that she had exceeded her budget by Rs.20 represented by (-20) .So she had to return few dresses.

### Learning Experience

• We have learnt integers in a very fun and interesting manner.

• The teacher has taught us to use integers in our day to day life, through many activities .

• We learnt integers with visuals and through a rhyme, which makes it interesting and easy to use.

• We wrote down what we wanted to learn and what we learnt and what we know through a KWL chart.
