Question 1 of 4
1. Question
Evaluate`9(+4)` (13)
Hint
Help VideoCorrect
Correct!
Incorrect
Same Sign = Find the SumDifferent Sign = Find the DifferenceMethod OneFirst, note that `9(+4)` will become `94`Since the signs are the same `( )` we will find the sum of the two numbers`9+4` `=` `13` Find the Sum `\text(Sum)` `=` `13` Insert the sign of the larger number `(9)` to the sum`9(+4)` `=` `13` Insert a negative sign since the larger number, `9`, is negative `13`Method Two`9``(+4)` `=` `94` `=` Recall, Start at `9`, then since `(+4)` becomes `4` which is negative, move left `4` places`9` `4` `=` `94` `=` `13` `13`

Great Work!
Incorrect
Same Sign = Find the SumDifferent Sign = Find the DifferenceMethod OneFirst, note that `6+(8)` will become `68`Since the signs are different `(+ )` we will find the difference of the two numbers`86` `=` `2` Find the Difference `\text(Difference)` `=` `2` Insert the sign of the larger number `(8)` to the difference`6+(8)` `=` `2` Insert a negative sign since the larger number, `8`, is negative `2`Method Two`6+``(8)` `=` `6` `8` `=` Recall, Start at `6`, then since `+(8)` becomes `8` which is negative, move left `8` places`6` `8` `=` `68` `=` `2` `2` 
Question 3 of 4
3. Question
Evaluate`2(9)` (11)
Hint
Help VideoCorrect
Excellent!
Incorrect
Same Sign = Find the SumDifferent Sign = Find the DifferenceMethod OneFirst, note that `2(9)` will become `2+9`Since the signs are the same `(+ +)` we will find the sum of the two numbers`2+9` `=` `11` Find the Sum `\text(Sum)` `=` `11` Insert the sign of the larger number `(9)` to the sum`2(9)` `=` `11` Insert a positive sign since the larger number, `9`, is positive `11`Method Two`2``(9)` `=` `2+9` `=` Recall, Start at `2`, then since `(9)` becomes `9` which is positive, move right `9` places`2` `+9` `=` `2+9` `=` `11` `11`

Nice Job!
Incorrect
Same Sign = Find the SumDifferent Sign = Find the DifferenceMethod OneFirst, note that `8(1)` will become `8+1`Since the signs are different `( +)` we will find the difference of the two numbers`81` `=` `7` Find the Difference `\text(Difference)` `=` `7` Insert the sign of the larger number `(8)` to the difference`8(1)` `=` `7` Insert a negative sign since the larger number, `8`, is negative `7`Method Two`8(1)` `=` `8` `+1` `=` Recall, Start at `8`, then since `(1)` becomes `1` which is positive, move right `1` place`8` `+1` `=` `8+1` `=` `7` `7`
