How to do the sum:-
write the point one under the other like this - (first write without the point add the point after writing the numbers)
52.75
+ 852.6
+ 18.4
3.46
= 927.21 is your answer. Remember carrying over and borrowing if it is minus.
346
The answer is 346. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
Add 210 and 262 together and divided them by 2 which is 236
184 * 100 to 96, subtract 4 * 96 to 104, add 8 * 104 to 88, subtract 16 * 88 to 120, add 32 * 120 to 56, subtract 64 * 56 to 184, add 128 See the pattern here? you alternate subtraction and addition in between each two numbers and double the value to add or subtract each time.
It isn't clear according to what rule you want to rearrange them. You can add them in any order; the result is the same.
1 + 202 + 193 + 184 + 175 + 167 + 148 + 139 + 1210 + 11All numbers that add to make 21 :)
The answer is 1335. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.

Yes there is. For big numbers it's usually harder to divide. So let's say you want to see if 346 is divisible by 11. First, you add up every other digit in the number. 3 + 6 = 9 4 + 0 = 4 Then you subtract the smaller answer from the bigger one. 9-4=5 If the answer you get is divisible by 11, then the whole number is. Therefore, 346 is not divisible by 11. Hope this helps
184
(1*2)+1=3 (3*2)+2=8 (8*2)+3=19 (19*2)+4=42 (42*2)+5=89 (89*2)+6=184 Basically the number times two and then add the the number it is in the sequence...i.e. 1 is the first number so add one, 3 is the second number so add two, etc.
