Step-by-step explanation:

yan po yung lumabas sa kalkyula ko sorry kung mali

Question:

1).9+8+(-6)= 11

2).(-13)+(-8)+5= -16

3).-63-(35+12)= -16

4).2×(-3)×(-5)= 30

5).-72 ÷9+8=0

Solution:

1. 9+8+(-6)

9+8=17

17+(-6)=11

2.(-13)+(-8)+5

-13+(-8)=-23

-21+5= -16

3. -63-(35+12)

35+12=47

-63+(47)= -16

4. 2×(-3)×(-5)

2(-3)=-6

-6(-5)=30

5.-72÷9+8

-72÷9=-8

-8+8=0

You must noted:

-Use MDAS (Multiplication, Division, Addition, and Subtraction) before answering to identify what number should you compute first.

-The number have highest sign (positive or negative) must be copy to your answer

ex:

7+-18=-11

-18 is the highest number so you must copy it's sign

-Also always remember the rule in multiplication and division.

Positive×Postive=Positive

Negative×Negative=Positive

Negative×Postive=Negative

Positive÷Postive=Positive

Negative÷Negative=Positive

Negative÷Postive=Negative
