100
#1. The sum of 25 and -30 and the reason why.
What is -5 because there's more negatives than positive?
100
#5. The scholar who wrote the correct rewrite and the reason why.
Marcus: -10 - -15 = -10 + -15
Dawn: -10 - -15 = 10 + 15
Jay: -10 - -15 = -10 + 15
Who is Jay because he doesn't change the first number, changes the operation, and changes the second number to its opposite?
100
#9. The reason why the absolute value is positive.
What is the absolute value is the distance from zero and distance is always positive?
100
#13. This is an expression that represents 7 withdrawals from a bank account where each withdrawal is $50.
What is 7 * -50?
Withdrawal is taking out money from a bank account. It is negative.
100
#17. The solution to a - b, if a = -9 and b = 10.
What is -19?
a - b = -9 - 10 = -9 + -10 = -19
200
#2. The solution to all three expressions in this order.
-12 + 15 = ?
12 + -15 = ?
-12 + -15 = ?
What is 3, -3, and -27?
200
#6. These are ALL the pairs of expressions that are equivalent.
A. -3 - 5 and -3 + -5
B. 25 - 10 and -25 + 10
C. -9 - (-6) and -9 + -6
D. 18 - (-4) and 18 + 4
E. 11 - 2 and 11 + -2
What are pairs A, D, and E?
Keep first number, change operation, change second number to its opposite.
200
#10. The distance between -8 and 12.
What is 20?
200
#14. The sign of the product of 100 negative numbers and the reason why.
What is positive because we are multiplying an even number of negative numbers, which means every negative sign will be paired with another?
200
#18. The math vocabulary word for the relationship between P and S.
What are opposites or additive inverses?
300
#3. The situation that gives a final value of zero and the reason why.
A. Starting with -$10 and losing another $10.
B. A bird starts at 12 feet above sea level and ascends 12 feet.
C. A temperature of -20 degrees rises 20 degrees.
D. Increasing a score of 55 points by 55 more points.
What is Situation C because -20 after an increase of 20 would equal to 0?
-20 + 20 = 0
300
#6. The solution to the following expression:
-85 - (-10)
What is -75?
-85 - (-10) = -85 + 10 = -75
300
#11. The solutions to the following expression, in this order.
|-9| + |10| = ?
|-9 - 10| = ?
|-9 + 10| = ?
What are 19, 19, and 1?
|-9| + |10| = 9 + 10 = 19
|-9 - 10| = |-19| = 19
|-9 + 10| = |1| = 1
300
DAILY DOUBLE
#15. The solution to the following expression, using GEMDAS.
18 ÷ -9 × 12 ÷ -6
What is 4?
18 ÷ -9 × 12 ÷ -6 = -2 × 12 ÷ -6 = -24 ÷ -6 = 4
300
#19. The solution of the following expression:
S - Q
What is 8?
S - Q = 5 - -3 = 5 + 3 = 8
400
#4. The solution to -50 + 20 + -25 + 30
What is a sum of -25?
-75 + 50 = -25
400
DAILY DOUBLE:
#8. The solution for the following expression:
12 - -8 + -4 - 10
What is 6?
12 + 8 + -4 + -10
20 + -14 = 6
400

C. |10 - -10|
D. |-10 - 10|
E. |-10 + 10|
What are A, B, C, and D?
A. 10 - -10 = 10 + 10 = 20
B. |10| + |-10| = 10 + 10 = 20
C. |10 - -10| = |20| = 20
D. |-10 - 10| = |-20| = 20
E. |-10 + 10| = |0| = 0

C. -(-9)(-2)
D. (-1)(4)(-6)
E. -(-8)(10)(-3)(6)(-9)(-1)
What are A, C, and E because all have an odd number of negative signs, which would make the product negative?

#20. The sign of the following expression, assuming that x is a nonzero integer, and the evidence to support.
4x
A. Positive
B. Negative
C. Sometimes Positive and Sometimes Negative
What is C?
x can equal 5 or -3 since they're both nonzero integers
4(5) = 20
