When we have mixed signs we need to make it a negative. A plus and a minus or a minus and a plus are made into a minus by default.
With that in mind the question would not turn into 1 - 2 =
From here we take the sign of the bigger number. The bigger number would be negative 2 and we put it as the first part of our solution
This next step might be easier with a number line from -5 to 5
We start at positive 1 on the number line. From here we need to go left because when subtracting you go left. We move two spaces to the left. So the one goes to 0 and then it goes to -1
The answer would turn out to be <u>negative one</u><u>(</u><u>-1</u><u>)</u>
<u>1</u><u> </u><u>-</u><u> </u><u>2</u><u> </u><u>=</u><u> </u><u>-</u><u> </u><u>1</u>
HOPE THIS HELPED!!! PLEASE DONT FORGET TO PUT THIS ANSWER AS THE BRAINLIEST. ALSO, LEAVE A HEART AND A 5 STAR TO LET PEOPLE KNOW IN THE FUTURE THAT THIS IS THE CORRECT ANSWER WITH A CORRECT EXPLANATION!! HAVE A GOOD DAY!
A number that can be written
Given:
2 years ago - consumer price index 1,200 per month
current year - consumer price index 1,400 per month
Inflation rate = [(Consumer price index current - Consumer price index previous) / Consumer price index previous ] * 100%
Inflation rate = [(1400 - 1200) / 1200] * 100% = (200 / 1200) * 100% = 16.67%
Since 2 years has passed, the 16.67% inflation rate is good for 2 years. We simply divide the inflation rate by 2 to get the annual inflation rate.
16.66% / 2 = 8.33%
The annual inflation rate for the past two years is 8.33%
I’m not sure if you’re looking for a specific answer, but on a broad spectrum science is typically just applied mathematics. Math can be incorporated into all sciences, especially physics. On occasion, science can also be included in math, like when using derivatives to find the acceleration of a moving object. All in all though, the two subject are very connected.
