Exponents The E in PEMDAS
Exponents • Exponents are used everyday you may just not know it. 32 is an exponent but which number is verified as an exponent? The two! So in the numbers below what are the exponents? 42 35 83 Exponents are actually very close to multiplication problems. 42 is the same as 4x4. You may wonder why is there a 2 not a 4 as the exponent. Well the two says that it’s two fours multiplying each other which says 4x4.
Squaring • Squaring may seem weird, but is actually is the same as using exponents. Only when there is a 2 is it called squaring. 32, 42, and 82 are all used when squaring. In area squaring is used very often. Three inches squared is an example.
PEMDAS properties • PEMDAS is the order of operations. The order of operations is Parentheses, exponents, multiplication, division, addition, and subtraction. PEMDAS shows that parentheses are 1st and exponents are 2nd. If parentheses are not there exponents are to be done next. Here is an example. 33x2-6= 27x2-6= 54-6=48 final answer is 48
