4 = 3 + 1 so 4 + 9 = (3 + 1) + 9
Then, by the associative property, = 3 + (1 + 9) = 3 + 10 = 13
You can make 10 using four 4's by using the following expression: ( (4 + 4) + \frac{4}{4} ). Here, ( 4 + 4 ) equals 8, and ( \frac{4}{4} ) equals 1, so when you add them together, you get 9. However, to reach 10, you can adjust the expression to ( 4 \times 2 + 4 - 4 ), which simplifies to ( 8 + 2 = 10 ).
U add 3 to make a whole
0.44
4
3.68 + 0.32 = 4
1 add 4 is 5 and 2 add 3 make 5. 5 add 5 make 10 so 2 x 10 is 20
34
5 + 9 = 5 + (5 + 4) = (5+5)+4 = 10+4 = 14 Much easier to do in your head than to type out. Practice it. Makes for subtraction much easier once you get the hang of it. ■
1 pound 10.
to make it a mixed number, you do 26 next to 4/10 so it would be 26 4/10. if you want to make it an improper fraction you do 26/1 and make it 260/10 and add 260 and 4 to get 264/10. so the answer is either 26 4/10 or 264/10. it sounds complicated but im in honors math.q
Multiply by 4 and add 10.

If we add -10 and -2 and -4, we get -16.
39.0625 = 10/4 * 10/4 * 10/4 * 10/4
You can make 10 using four 4's by using the following expression: ( (4 + 4) + \frac{4}{4} ). Here, ( 4 + 4 ) equals 8, and ( \frac{4}{4} ) equals 1, so when you add them together, you get 9.

It is 4/10 because 6/10 plus 4/10 = 1
Well, isn't that a happy little math problem! Let's take a closer look at it. If we add 4 + 4 + 4 + 4 + 4 together, we get 20, not 10. It's easy to make a mistake, but don't worry, mistakes are just happy little accidents that help us learn and grow.
