Grant finds the difference of 360 and 127 as shown. What is Grant's mistake?

Grant should have subtracted the ones first and

the hundreds last.

Grant did not regroup the 2 hundreds when he

subtracted 7.

360

- 100

260

20

240

7

243

Grant should have subtracted 120 instead of 20.

Grant did not regroup the 4 tens when he

subtracted 7

Done

Hey

D. Grant did not regroup the 4 tens when he  subtracted 7.

Step-by-step explanation:

In the process of subtraction, regrouping is important so that each digit in the given numbers are placed appropriately before the required arithmetic operation is performed.

The correct step to Grant's solution are:

360 - 100 = 260

260 - 20 = 240

240 - 7 = 233

Grant's final answer ought to have been 233.

Going through his solution, he made a mistake while subtracting 7 from 240. He failed to regroup the 4 tens when he  subtracted 7 from 240. Thus the essence of his wrong answer.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
