----(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-x¯¯|
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.
NOTE THAT WHEN U SEE SOMETHING LIKE THE ABOVE TWO EXAMPLES, U WILL NEED TO DRAW A TABLE..


YOU NEED TO KNOW THESE ALSO:
MATHS CODES:
1) ,(comma) means next line.
(e.g)
x : 1,2,3
fx : 4,5,6
fx-xbar : 7,8,9

x|fx |x¯¯|
1| 4 | 7 |
2| 5 | 8 |
3| 6 | 9 |

2)*=multiplication sign.

3)^ = Riase to pwer

4)P also means raised to power eg 10P6 means 10 raised to power six.

5)log3(base 4) ..Note:the base must be SUBSCRIPT .

6)x bar = mean symbol(x¯¯)

7)Pie = pie symbol eg Area of a circle is (Pie r2).

8)Tita = θ eg Sinθ.

10)Root or Rut or Sqrt or sqr root = √ ; eg Root2 means √2

11)/ means ÷

12)----(1) means equation 1
We learnt that some candidates who have registered for the 2017 UTME have been given a date to reprint their registration slips as to know the exact venue or centre, Time and date they will take the examination.

The date to reprint the registration slips is indicated on the candidates' registration printout.

Many candidates may not have taken note of this.


According to the information, many candidates were given April 25th, 2017 to reprint their registration slips to know their examination details.

However, what we do not know if all the candidates that registered so far were given the same date to reprint their slips.

So we would like to know from Myschoolers who have registered for 2017 UTME what date they were given to reprint their registration slips as indicated on their registration printouts.
