Arithmetic/Part I Review and Test

Notes

Remember that:

Any time a number smaller than (LESS than) 0 is added to a number larger than (GREATER than) 0 you would use subtraction as shown below:

   5+(-3)=5-3, therefore 5+(-3)=2

Any number subtracted from itself always equals 0.

Any number above 9 will always have more than one digit.

The number line is very important in calculating numbers smaller than 0.

Part I Test

<quiz display=simple points="1/1"> {Part 1 of 3.}

{ |type="{}"} $2+2=${ 4_2 }

{ |type="{}"} $2+4=${ 6_2 }

{ |type="{}"} $5+3=${ 8_2 }

{Part 2 of 3. Numbers greater than 9}

{ |type="{}"} $10+11=${ 21_2 }

{ |type="{}"} $12+12=${ 24_2 }

{ |type="{}"} $14+10=${ 24_2 }

{Part 3 of 3. Numbers smaller than 0}

{ |type="{}"} $-4-4=${ -8_2 }

{ |type="{}"} $-2+5=${ 3_2 }

{ |type="{}"} $5-(-2)=${ 7_2 }
