Hieroglyphics is a form of writing that uses signs and symbols and was used by ancient Egyptians.
The first known writing came from the Sumerians at least 5,000 years ago in the form of picture symbols,m used probably as a way to record farming transactions. This spread and matured into different languages' differing symbols. The most similar to it now would be the characters of Chinese and Japanese; other Mid-Eastern languages still (to English-speakers) look like symbols rather than language as alphabets. Eventually it evolved into shapes in Greek, and Anglican and Saxon combined with some Celtic portions to form Old English. As it spread and simplified, it morphed into the writing system we have today.
Numbers are conceptual, but the symbols (or pictures) you use when you write them down on paper are called numerals. The Arabic symbol we use for the number "five" is 5, but the Roman numeral for the same number is "V". Other alphabets have corresponding symbols that represent numbers in those systems.
Although hieroglyphics were used as a form of writing, they were different from the alphabet because they were pictographs (picture images that represented different thoughts and concepts), rather that characters that are combined to communicate representative ideas.
