• Calculate the solutions without a calculator.1) 48 ÷ (4 + 4) 2) (6 - 4) × 49 ÷ 7 3) 20 ÷ (4 - ( 10 - 8))
Joke of the day
There are three types of people in the world, those who can count and
those who can't.
Comparing integers
• Positive numbers are always larger than negative.
• When both positive, highest place value wins.• When both negative, the one with the
smallest absolute value is the largest.
Examples
1. 26,892 28,6972. 5 -33. -5 -4
Decimals
• Largest integer part is largest.• Compare decimal places from left to right until
there is a difference.
Examples
1. 9.57 0.57 2. 0.05 0.009
Now, it’s your turn…
• Complete the worksheet independently.• Be prepared to present your solutions with
the class.
Exit Slip• Find the solutions.1) 12 √ 123 2) 833 ×78 3) 614 − 99 4) 988 + 83 • Which number is larger?5) 618 or 718 6) 6.8 or 6.10
