THE SECRET ART OF MATHEMATICS

11 AND GENERATION OF 11.

ALREADY YOU HOW TO MULTIPLAY BY 11.

BUT DID YOU KNOW HOW TO MULTIPLAY BY 22 ? ? ? ? ? ? BE’COZ…….,
THE 22 IS THE SECOND GENERATION OF 11.

EXAMPLE : – 45 X 22 = ? ? ?

THEARE IS NO HARD WAY USE THIS SIMPLE IDEA

STEP NO 1 ) 1ST DOUBLE THE MULTIPLICANT OF 45 …… YES YOU GOT 90…….

STEP NO 2 ) TOOOOOOOO SIMPLE SPLIT THE 90 TO LEFT AND RIGHT SIDES LIKETHIS………………… 9 — 0

STEP NO 3 ) DON’T THINK MOOOOORE ADD LEFT AND RIGHT THEN INSERT TO MIDDILE SPACE LIKE THIS (9+0=9)
9 9 0

THEARE FOR 45 X 22 = ???
————-
9 9 0
————-

TO MORE DIGIT NUMBERS ???

EXAMPLE : – 22366813 X 22 = ?
1ST ADD ZERO’S LEFT AND RIGHT .
0 2 2 3 6 6 8 1 3 0 X 22 = ??
THEN ADD RIGHT TO LEFT IMMEDIATLEY DOUBLE THE VALUE THEN TO TAKE ANSWER .

LIKE THIS 0 2 2 3 6 6 8 1 3 0 X 22 = ?
————————
4 9 2 0 6 9 8 8 6
————————-
1 2 2 2 1 ( CARRY FOR WARD)

0+3 = 3 DOUBLE IS 6,
3+1 = 4 ,, ,, 8, (C.F=0)
1+8 = 9 ,, ,, 18, (C.F=1)
8+6 = 14 ,, ,, 28+1 (C.F=2)
6+6 = 12 ,, ,, 24+2 (C.F=2)
6+3 = 9 ,, ,, 18+2 (C.F=2)
3+2 = 6 ,, ,, 12+2 (C.F=1)
2+2 = 4 ,, ,, 8+1 (C.F=0)
2+0 = 2 ,, ,, 4….
