Question

3. Simplify the following using the
associative property of addition of
integers.
a) (-6) + (-17) + (-4) + (-3)
2-3) b) (-79) + 56+(-21) + 4
c) 87 +(-7) +13 +(-3)
d) 64 + (-176) + (-24) + 36
4. In a quiz, group A scored -34, 12, 3
Le
and group B scored 15, 5, -32 in three
successive rounds. Which group scored
more? Can we say that integers can be
added in any order?
5. Verify: [(-16) +6] + 5 =(-16) + (6 + 5).

Answer 1

Step-by-step explanation:

According to the associative property of addition, the sum of three or more numbers remains the same regardless of how the numbers are grouped.

Q3.

• -31
• -40
• 90
• 100

Q4.

• Group A scored: -34 12 3
• Group B scored: 15 5 -32
• Group A= (-34)+(12)+(3) = -19
• Group B= (15)+(5)+(-32) = -12
• GROUP-B scored more than Group-A.
• We can say that we can add integers in an order.

Q5.

• [(-16) +6] + 5 =(-16) + (6 + 5)
• (-10)+5 = (-16)+ 11
• -5 = -5
• It is associative property of Addition.
