(i) only B. (i) and (iii) only C. (iii) only D. (i), (ii), (iii), and (iv) Answer: Our modern base 10 number system uses place-value notation. Place-value notation uses same symbol for over and over again to stand for different orders of magnitude. For example, the number digit “1” is used for 1, 10, 100, 1000, and so on. ----------------------------------------- The ancient Egyptian number system is a simple additive base ten system. A simple additive base system uses a different symbol to represent each number. To represent a number that is large, or a sum of small numbers, the symbols are strung together: Using the Roman number system as an example (Roman numerials can be typed on my keyboard, Egyptian numerials cannot be typed on my keyboard), LXXX = L(a value of 50) + X(a value of 10) + X(a value of 10) + X(a value of 10) = Eighty. LXXX = Eighty The Egyptian system does not have a 0 (zero), is not subtractive, or multiplicative. ----------------------------------------- Your question is: which of the following is (are) attributes of the Egyptian number system? The answer to your question is: Choice A (ADDITIVE) Thanks for writing. Staff www.solving-math-problems.com
