Please Help Me. What Is The Answer To This Math Problem?

Please help me. What is the answer to this math problem?

 

Answer:

0 and -1, respectively.

Step-by-step explanation:

To add or subtract fractions, they must be similar where the denominators are the same. If not, convert to similar terms by finding their least common denominators (LCD):

1)  (+1/2) + (+2/3) + (-1 1/6)  ⇒  LCD: 6

Divide the LCD by the denominator of each term, then multiply the result by the numerator to determine the equivalent fraction:

+3/6 + 4/6 - 7/6

= (3+4-7)/6

= 0/6

= 0

When the numerator is 0, the result is always 0.

2) - (+1/2) + (+2/3) + (-1  1/6)

=  -3/6 + 4/6 - 7/6

= (-3 + 4-7)/6

= -6/6  ⇒ when dividing integers with unlike sign, the result is positive.

= -1

Why Did The Catholics Change Their Way Of "Transubstantiation"?

Why did the catholics change their way of "transubstantiation"?   Before we go on with the topic, what is Transubstantiation? Transubstantiation is the turning ordinary bread and wine into the body and blood of Christ but still remain in the appearance of bread and wine. After 1969, the start of Second Vatican Council, catechism is not that taught anymore so the Eucharist, unfortunately, is not appreciated by parishioners anymore . Before 1969, the body of Christ is receive reverently , kneeling and on tongue . Now, we only receive him standing and using our bare and sinful hands. Are we worthy of touching our lord and savior in the form of bread by using our hands? In John 20:17, Christ said not to touch him : John 20:17 Jesus says to her, "Do not touch Me, for not yet have I ascended to the Father. Now go to My brothers and say to them, I am ascending to My Father and your Father, and to My God and your God." We can change our mindset towards the eucharist b

How Is Electricity Generated

How is electricity generated   Answer: Electricity generation is the process of generating electric power from sources of primary energy. For electric utilities in the electric power industry, it is the first stage in the delivery of electricity to end users, the other stages being transmission, distribution, energy storage and recovery, using the pumped-storage method. Explanation: The fundamental principles of electricity generation were discovered in the 1820s and early 1830s by British scientist Michael Faraday. His method, still used today, is for electricity to be generated by the movement of a loop of wire, or disc of copper between the poles of a magnet. Central power stations became economically practical with the development of alternating current (AC) power transmission, using power transformers to transmit power at high voltage and with low loss. In 1870, commercial electricity production started with the coupling of the dynamo to the hydraulic turbine. In 1870, the
