The answer is digit sum method.
Digit sum method is method used to check the sum of sum numbers. If the sum of all of the digits of numbers is equal to the sum of all of the digits of the total sum, then the arithmetic process was correct.
We need to check the sum of <span>104+34+228+877:
</span>104 + 34 + 228 + 877 = 1243
Let's first summarize the digits of individual numbers:
104 *** 1 + 0 + 4 = 5
34 *** 3 + 4 = 7
228 *** 2 + 2 + 8 = 12 *** 1 + 2 = 3
877 *** 8 + 7 + 7 = 22 *** 2 + 2 = 4
Now, let's sum these sums:
5 + 7 + 3 + 4 = 19 *** 1 + 9 = 10 *** 1 + 0 = <u><em>1</em></u>
Then, let's summarize the digits of the total sum:
1243 *** 1 + 2 + 4 + 3 = 10 *** 1 + 0 = <u><em>1</em></u>
Since the sums of the digits on the both sides of equation is 1, than the arithmetic process was correct and the sum of <span>104 + 34 + 228 + 877 is really 1243.</span>
Answer:
The Factor of expression using the greatest common factor is 
Step-by-step explanation:
Consider the provide expression.

We need to Factor the expression using the greatest common factor.
First look at the coefficients of the variable.
The coefficients are the factor of 2.
Variable p is the greatest common factor in the provided expression.


Hence, the Factor of expression using the greatest common factor is
.

Answer:
5+3 is Amy, so Amy is 8
Step-by-step explanation:
So, lets say amy is a
and gabriella is g
WE know that g=5, because gabriella is 5 years old
And, Gabriells is younger than Amy, so we need to add to get Amy's age
So, 5 ( Gabriella's age ) + 3=Amy
So, 5+3= Amy
So Amy is 8
