[255] [256] There are small pockets of molten rock in the upper mantle, but these make up a tiny fraction of the mantle's volume. [257] The Earth's outer core is liquid, but it is liquid metal, not rock. [258] The Amazon rainforest does not provide 20% of Earth's oxygen. This is a misinterpretation of a 2010 study which found that approximately ...
The main arithmetic operations are addition, subtraction, multiplication, and division. Arithmetic is an elementary branch of mathematics that studies numerical operations like addition, subtraction, multiplication, and division. In a wider sense, it also includes exponentiation, extraction of roots, and taking logarithms.
