New Multiplication C

How to multiply 2 double-digit numbers.

24 x 31 = (20 + 4)(30 + 1)
= 600 + 20 + 120 + 4
= 744

59 x 75 = (50 + 9)(70 + 5)
= 3500 + 250 + 630 + 45
= 3545 + 880
= 4425

How to multiply 2 triple-digit numbers.

324 x 531 = (300 + 24)(500 + 31)
= 150000 + 9300 + 12000 + 744
= 150744 + 21300
= 172044

256 x 475 = (200 + 56)(400 + 75)
= 80000 + 15000 + 22400 + 4200
= 84200 + 37400
= 121600

Multiply double-digit number x triple digit number.

26 x 431 = (20 + 6)(400 + 31)
= 8000 + 620 + 2400 + 186
= 8186 + 3020
= 11206

329 x 45 = (300 + 29)(40 + 5)
= 12000 + 1500 + 1160 + 145
= 12145 + 2660
= 14805

New Multiplication B

How to multiply 2 triple-digit numbers
whose hundreds digits are both one (1).

104 x 117 = (100 + 4)(100 + 17)
= 10000 + 1700 + 400 + 68
= 12168

112 x 105 = (100 + 12)(100 + 5)
= 10000 + 500 + 1200 + 60
= 11760

The pattern is:
Note: r & s represent double-digit numbers.

1r x 1s = (100 + r)(100 + s)
= 10000 + 100s + 100r + rs
= 100 + 100(r+s) + rs
= 100 + 100(sum of numbers) + product of numbers

And the above two examples can now
be calculated mentally as follows -

104 x 117 = 10000 + 100(4+17)+ 68
= 10000 + 2100 + 68
= 12168

112 x 105 = 10000 + 100(12+5)+ 60
= 10000 + 1700 + 60
= 11760

New Multiplication A

How to multiply 2 double-digit numbers
whose tens digits are both one (1).

14 x 17 = (10 + 4)(10 + 7)
= 100 + 70 + 40 + 28
= 238

19 x 15 = (10 + 9)(10 + 5)
= 100 + 50 + 90 + 45
= 285

The pattern is:

1a x 1b = (10 + a)(10 + b)
= 100 + 10b + 10a + ab
= 100 + 10(a+b) + ab
= 100 + 10(sum of units) + product of units

And the above two examples can now
be calculated mentally as follows -

14 x 17 = 100 + 10(4+7)+ 28
= 100 + 110 + 28
= 238

19 x 15 = 100 + 10(9+5)+ 45
= 100 + 140 + 45
= 285
