The answer is she has 20 stamps from Europe, 18 stamps from Africa and 9 stamps from Asian. 18+9=27+20=47 47 stamps in all
It had a positive effect on the world, but for the humans those times it was a negative effect. Bcuz the Portuguese took slaves from Africa. so it was bad for humanity. But if the age of exploration hadn't happened the united states wouldn't be here. So it also has a positive effect. It depends on how u look at it.
No one knows. It happened before there was any writing, so there is no record of when it happened or who did it. Addition and subtraction are simple enough that many animals can perform it, albeit not quite well sometimes, even in the wild and without training. It is a natural Darwinian skill. For example, crows can count how many lions took down a gazelle behind a bush (out of site) and then count them as they come out again so it knows when it can scavenge freely (they sometimes have trouble with numbers bigger than 3). Undoubtedly, early humans could add and subtract reasonably well on the hunting grounds on the grasslands of Africa, before language. Multiplication would have come along as humans had more free time to think or calculate and the skill was probably improved on along with war and complicated hunting. Division is more complicated and may have only been used "intuitively" for a long time, until the ancient civilisations and cultures developed better mathematics (likely a Arabic, Egyptian, Mediterranean, Chinese or Indian culture).
