Transcript EDI NS1_3A Understanding positive integer powers of nonnegative

Today we will understand how
to identify, read, and write
positive integer powers of
nonnegative
integers.
Identify=to point out
Positive integer=whole numbers greater
than zero
nonnegative numbers=positive numbers
•
Positive integer- a whole number greater than 0.
•
Nonnegative integer- a whole number greater than 0.
•
Power or Exponent- a mathematical notation indicating the
number of times a quantity is multiplied by itself.
– A power or exponent is placed to the right of and above
another number.

It is important to know how to read and
write exponents because they are used
when finding the area of certain places.
It is on your grade level standards
probably all the way until you graduate
12th grade
What other reasons can you think of why
it is important to read and write
exponents?
