Describe an addition problem that you may need to regroup hundredths to solve

Solution:

Consider the problem of addition of two or more than two decimal numbers which includes hundredths can be solved by regrouping Hundredths

For example

3.098 + 4.7896+ 5.004

It can be written as

Addition of number on unit place = 3+4+5=12

Addition of number on their tens place ==0.7

Addition of number on their Hundredths place==0.17

Addition of number on their Thousandths place==.021

Number on ten thousandths place can be written as=0.0006

So, Sum = 12 +0.7 +0.17+0.021+0.0006=12.8916

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
