Well, it's like your fingers. You have 2 hands with five fingers each. So 5+5=10 figers like 2 fingers+2 fingers=4 fingers in all.
1 add 4 is 5 and 2 add 3 make 5. 5 add 5 make 10 so 2 x 10 is 20
Just add them regularly and if it is negative, then make it negative. Example: 2+2= 4 -2+(-2)= -4 Or 2+(-1)= 1

Add 1 and 3/7ths.
You cannot. And you cannot add parentheses to make it true either.
X2 + 4X + 4 Ask yourself, what factors of 4 add up to 4? (X + 2)(X + 2) or, more commonly expressed as, (X + 2)2
multiply 9 and 2....then add 4 and 5
-4 x 5 = -20 and -4 + 5 = 1.
2x9+4+2. When you multiply 2 and 9 you get 18. Then when you add 4 you get 22. When you add 2 you end up with 24.
When you add 34 plus 4 plus 2, you get an answer of 40.
make the 1/4 into 2/8 Answer: 8 and 5/8
31 + 5 + 3 + 2
