Question 1 of 4
1. Question
Evaluate`-3+14`- (11)
Hint
Help VideoCorrect
Nice Job!
Incorrect
Same Sign = Find the Sum
Different Sign = Find the Difference
Method OneSince the signs are different `(- +)` we will find the difference of the two numbers`14-3` `=` `11` Find the Difference `\text(Difference)` `=` `11` Insert the sign of the larger number `(14)` to the difference`-3+14` `=` `11` Insert a positive sign since the larger number, `11`, is positive `11`Method TwoStart at `-3`, then since `14` is positive move right `10` places`-3` `+14` `=` 
`-3+14` `=` `11` `11` -
Question 2 of 4
2. Question
Evaluate`8-(-7)`- (15)
Hint
Help VideoCorrect
Excellent!
Incorrect
Same Sign = Find the SumDifferent Sign = Find the DifferenceMethod OneSince the signs are the same `(- -)` we will find the sum of the two numbers`8+7` `=` `15` Find the Sum `\text(Sum)` `=` `15` Insert the sign of the larger number `(8)` to the sum`8-(-7)` `=` `15` Insert a positive sign since the larger number, `8`, is positive `15`Method Two`8``-(-7)` `=` `8` `+7` `=` Recall, Start at `8`, then since `-(-7)` becomes `7` which is positive, move right `7` places`8` `+7` `=` 
`8+7` `=` `15` `15` -
Question 3 of 4
3. Question
Evaluate`-5-(-2)`- (-3)
Hint
Help VideoCorrect
Keep Going!
Incorrect
Same Sign = Find the SumDifferent Sign = Find the DifferenceMethod OneFirst, note that `-5-(-2)` will become `-5+2`Since the signs are different `(- +)` we will find the difference of the two numbers`5-2` `=` `3` Find the Difference `\text(Difference)` `=` `3` Insert the sign of the larger number `(-5)` to the difference`-5-(-2)` `=` `-3` Insert a negative sign since the larger number, `5`, is negative `-3`Method Two`-5-(-2)` `=` `-5` `+2` `=` Recall, Start at `-5`, then since `-(-2)` becomes `2` which is positive, move right `2` places`-5` `+2` `=` 
`-5+2` `=` `-3` `-3` -
Question 4 of 4
4. Question
Evaluate`10+(-3)`- (7)
Hint
Help VideoCorrect
Well Done!
Incorrect
Same Sign = Find the SumDifferent Sign = Find the DifferenceMethod OneSince the signs are different `(+ -)` we will find the difference of the two numbers`10-3` `=` `7` Find the Difference `\text(Difference)` `=` `7` Insert the sign of the larger number `(10)` to the difference`10+(-3)` `=` `7` Insert a positive sign since the larger number, `10`, is positive `7`Method Two`10+``(-3)` `=` `10` `-3` `=` Recall, Start at `10`, then since `+(-3)` becomes `3` which is negative, move left `3` places
`10-3` `=` `7` `7`
