Give an example from everyday life of using positive and negative numbers.

There are many such examples.

The classic example is the use of thermometer readings. If the column or display of the thermometer shows a negative temperature, this means, at least, that the water outside is frozen and can be slippery. The lower the value, the warmer you should dress. The same is true at positive temperatures. For example, for motorists – the transition from winter tires to summer tires.

If the phone has a minus, it means that outgoing calls are not available and the account needs to be replenished. A positive number on the balance sheet tells you that you can use the connection in full.
