six. hello
if you could type that question, you can use a plain calculator. get one will ya!!! just press 5 + 1 =. there's your answer!
(Double plus 1 of 5) plus 5 = 16 Double plus 1 of (5 plus 5) = 21
Note that the reason there exists a technique called multiplication is so that we do not have to perform tedious and lengthy series of addition such as the one you have presented. So, you have given us 24 of the number 5 to add. 24 x 5 = 120. (Addition form) 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 120
for 5+5+5=550, you'll have to add one line to the plus so the plus will look like a four. 5+545=550
1/5 + 3/5 + 1/5 = 1
1 plus 1 =2 + 1=3+1=4+1=5+1=6 but in that caase it'd have 5 plus' and in the question it only has 4 so this is rubbish
One method is (10×4)+(5×3) = 55 (or mentally add up from left to right).
One way would be 5 plus 9 plus 0.4 plus 0.31
5 eighteenths. 5/18
They add up to 4/5
1/5 + 1/5 = 2/5
1 1/5 + 3 2/5 + 4 1/5 = 8 4/5
Yes.
