# Easy Steps In Multiplying Two Digit Numbers Mentally

Easy Steps In Multiplying Two-Digit Numbers Mentally

In this hub I present some solutions in multiplying two digit numbers mentally. I present here several examples with easy steps to follow in order to compute mentally. Hope this hub will be helpful to you.

Example Number One :

Multiply 25 by 42: This is same as multiplying 25 by (40 + 2)

Step One : Multiply 25 by 40 mentally. .25 * 4 = 100 then append 0 will yield 1000

Step two :Multiply 25 by two which gives 50.

Step Three : Add 1000 and 50 which gives 1050.

Therefore 25 * 42 = 1050

Example Number Two :

Multiply 26 by 33: This is same as multiplying 26 by (30 + 3)

Step One : Multiply 26 by 3 which gives 78. Append 0 will give 780.

Step Two : Multiply 26 by 3 again which gives 78.

Step Three : Add 780 and 78. The sum is 858

Therefore 26 * 33 = 858

Example Number Three:

Multiply 50 by 15 : This is same as multiplying 50 by (10 + 5)

Step One: Multiply 50 by 10 which gives 500.

Step two : Divide 500 by two which gives 250

Step Three : Add 500 and 250 which gives 750.

Therefore 50 * 15 = 750.

Example Number Four:

Multiply 35 by 44: This is same as multiplying 44 by (30 + 5)

)Step One: Multiply 44 by 30 by multiplying first 44 by 3 which gives 132 then append 0 will become

1320.

Step Two : Multiply 44 by 5 by dividing 440 by two which gives 220.

Step Three: Add 1,320 and 220 will give 1,540.

Therefore 44 *35 = 1540.

Example Number Five :

Multiply 27 by 56: This is same as multiplying 27 by (50 + 6)

Step One : Multiply 27 by 50 by multiplying first 27 by 5 which gives 135 then append 0 will become

1350.

Step Two : Multiply 27 by 6 which gives 162.

Step Three: Add 1550 and 162 which gives 1712.

Therefore 27 * 56 = 1712.
