Want to square a number that ends in 5?
35×35=?
Do the trick I learned from Vedics Math.
The tens spot add one to the top than multiply the two together 3 turns to 4 than multiply 4×3=12
Than just multiply the ones spot.
5×5=25
35×35=1225
Math Trick For multiplying 11
I taught my children the trick for 11 when they were 6 and 7.They are 10 and 12 now.
11×54=?
5 in front leave a space then put 4 in back at two together to get middle number.
11×54= 594
11×78=?
Little tricky
7_8 to get middle # at 7+8=15
Do not put 15 in middle
only one # fits and that is the 5
(7+1)858
11×78=858
Remember to carry the # from the tens spot to the hundreds spot.
What about bigger #’s?
11×1324=?
Put the 1 in front the 4 in back and for the middle #’s just add from left to right.
1(1+3)4(3+2)5(2+4)6 4
11×1324=14564
Remember if one of your #’s is more than 9 just carry to the number in front.
11×1823=?
1(1+8)9(8+2)10(2+3)5 3
1(9+1)10 053
(1+1)20053
11×1823=20053
Getting tired so I will stop for now but will be back again soon with more speed math tricks.
