BODMAS stands for Brackets, Order, Division, Multiplication, Addition, Subtraction. It's a mathematical rule for solving expressions consistently. Dr Peter Price's 2012 Facebook question showed only 26% correct answers
e^0 equals 1 for all numbers. Exponentiation is iterative multiplication of base by itself. Positive exponents (n) multiply base n times. Negative exponents (n) are reciprocal of base
Arithmetic studies numbers and their relationships in mathematics. Term "arithmetic" derives from Greek "arithmos" meaning "number". Gauss extended term to include more advanced topics in 1801
Order of operations determines which operations to perform first in mathematical expressions. Higher precedence operations are performed before lower precedence ones. Calculators generally evaluate operations from left to right
Exponentiation means multiplying a base number by itself a certain number of times. The exponent indicates the number of times to multiply the base
Exponents consist of base and exponent (a^b). Leftmost exponent shows base being multiplied, rightmost shows number of times. Exponents make long multiplications more efficient
