rais means raise to power
^ means raise to power
sqr rut/ squar rut means square root
----(1) means equation 1
yr means year
f(x-xbar) means x MINUS x BAR as in statistics which means that MINUS WILL BE ON TOP OF x.
, (Comma) means NEXT LINE, THIS MEANS THAT THE FOLLOWING NUMBER IS UNDER THE NUMBER IT IS FOLLOWING i.e UNDER. It is usually used during STATISTICS when drawing a table.
EXAMPLE 1.
X:1,2,3,4,
FX: 4,6,8,10
FX-Xbar: 10,8,6,4,
DRAW A TABLE WITH X|FX|(FX-Xbar)
The above statement means that:
~For X, it has 1 2 3 4 5 6 under it. which means 1 is under 2, 2 is under 1, 3 is under 2, 4 is under 3 and so on...
~Under FX you have 4, then 6 under 4, then 8 under 6, then 10 under 8, then 12 under 10.....
~Under FX-Xbar you have 10, then 8 under 10, then 6 under 8, then 4 under 6, then 2 under 4, then 1 under 2....
IN A CLEARER WAY:
� comma means NEXT LINE(e.g)
x : 1,2,3
fx : 4,5,6
fx-xbar : 10,8,6,4
x|fx |fx-xÃ�¯Ã�¯|
1| 4 | 10 |
2| 6 | 8 |
3| 8 | 6 |
4| 10| 4 |
ANOTHER EXAMPLE:
Class interval: 60-64,65-69,70-74,75-79,80-84,85-89,90-94,95-99.
X: 62,67,72,77,82,87,92,97.
F: 2,3,6,11,8,7,2,1.
FX: 124,201,432,847,656,609,184,97.
F(x-x bar)2: 561.12,414.18,273.36,33.66,84.48,476.42,351.12,333.06
MEANING OF THE ABOVE EXPRESSION:
Bar means Minus on top of d number or Variable and comma means next line which means each of them are unda. Eg 60-64 is unda Class interval, then 65-69 is unda 60-64,etc .So comma means unda.

Learn How You Can Now Send Anyone A Direct Message on Twitter, Even If You Don’t Follow them
Twitter has re-added a feature that was once tested in 2013. It now allows you to send anyone on Twitter a direct message but it is an optional feature.
Previously you can only receive private messages from people that you follow and follow you back, but there is now an option to switch things that will allow you to receive DMs from anybody.
The new setting is turned off by default – likely to prevent harassment – but you can switch things up in your settings menu.
The message update is probably Twitter’s answer to Facebook’s Whatsapp and Facebook Messenger.
