7.1 – Day 2 Square Roots and Order of Operations Essential Question: How can we use order of operations to solve problems with square roots?

Vocabulary - Review Square Root: A number that when multiplied by itself equals the given number. Every positive number has a positive and negative square root! Except Zero only has one square root which is zero. Perfect Square: A number with integers as its square roots. : A radical sign Radicand: The number under the radical sign
