Negative numbers can be used for weather, when we talk about temperature that is below zero.
The tally marks I'm familiar with cannot have negative numbers because they are used to count real things and there cannot be a negative apple
Negative numbers are often found in measurements. They are used to represent numbers that have sunk below 0 (ex: temperature, debt) or have become the inverse of a number (velocity, energy, negative exponents). Without machines of sorts negative numbers are very rare in everyday life, but so are very large numbers or very small numbers.
That's like asking, "How do you use numbers in real life". Maybe you're referring to the negative portion, in which you use when you owe something. Postive numbers are used often also, say on a food label or a price tag. Zero, is used when you have nothing, bur you don't owe anyone. This would happen a lot, yes?
natural numbers are used in real life for counting, adding, subtracting and even for calculting money purposes
