Can someone figure out these math Problems?

Question

This problem starts with Letters as numbers and then an individual letter counts as a number.

For example:
AD
+ AD
----
OH

Is the same as
35
+35
------
70

Rules of this problem:
1.If a letter is used once as a number it is the same exact number
2.Different letters in the problem always stand for a different number
3. A letter standing for 0 can never start as a number with more than one digit. (Example: it cant be 05 or 005 as the answer but it can be 503 or 500 or 530)


The Problems:

1. A B B
- A
---------
D D


2. S S
+ E E
---------
S S T


3.A B
+B C
-------
A D E

4. S E N D
+ M O R E
--------------
M O N E Y






Thank you for helping me~!

The rules stand for each seperate problem so The letters in number 1 arent the same as number 2 and so on and so on

Answer 1

1 DD must be 22 or 33 or.. 99. If A is 0 to 9, then DD must be 99, A = 1, and B = 0. (100 - 1 = 99)

2 The highest you can get by adding 2 2-digit numbers is 198 (99 + 99) so S=1. E = 9 and T = 0 (11+99 = 110)

3. A=1 B=8 C=4 D=0 E=2 (18+84 = 102)

4. M=1

Answer 2

on your case, you're a million/8 Irish and (something) 7/8 black. The fraction 7/8 is quite 87.5%. So asserting you're 87% black (however quite it may around as much as 88%) is truthfully the comparable as asserting 7/8 black. in particular, to be certain the ethnic possibilities or fractions of somebody, you upload up each and all the fractions of the mothers and fathers, for my section upload jointly any comparable ethnicities, and divide each thing by applying 2. as an occasion, in my case my mom is one hundred% Irish and my father is a million/2 French and a million/2 Irish. So my ethnicity is: [ (one hundred% Irish) + (50% French + 50% Irish) ] / 2 = [ one hundred fifty% Irish + 50% French ] / 2 = (one hundred fifty/2)% Irish + (50/2)% French = seventy 5% Irish + 25% French you're able to do the comparable with fractions and land up with the comparable effects (3/4 Irish, a million/4 French). it quite is considering which you in many cases get a million/2 of your ethnicity out of your mom, and a million/2 out of your father. in addition, you ought to take a million/2 of their ethnicities, and then upload up the fractions. you will constantly get the comparable effects the two way, via fact the approaches are algebraically equivalent. Getting decrease back on your loved ones. If we predict the 7/8 & a million/8 is actual, and that your father is one hundred% black, then your mom could must be a million/4 Irish and 3/4 black. this form you get (a million/4 Irish + 3/4 black + a million/a million black) / 2 = (a million/4 Irish + 7/4 black)/2 = a million/8 Irish, 7/8 black. this could propose that her mom (your maternal grandmother) is a million/2 Irish and a million/2 black. On an factor observe, there is quite no way you're able to be a million/3 of something. If we predict that ancestors constantly hint decrease back to human beings of a few one hundred% ethnicity, and a guy or woman has 2 and easily 2 organic and organic mothers and fathers, then you definately can in basic terms artwork in multiples of powers of a million/2. you won't be able to upload up halves, quarters, eighths, and so on. and get thirds. EDIT: I initially wrote "African" for "black", no longer via fact i assumed I had to be %., yet via fact i assumed geography become the defining factor right here in basic terms as that's for "Irish". yet then i found out that "black" can consult with ethnicities technically no longer from the continent and vice versa so I went with the greater accepted term.

Tell us what the numbers the letters represent?
