How do you solve to get 36.156?

jimthompson5910 (jim_thompson5910):

the first step is to ignore the decimal points completely (we'll reintroduce the decimal point back in later when we're done multiplying the numbers) so we have 786 times 46 here is one way to multiply them out this is known as the lattice multiplication ------------------------------------------- the first step with lattice multiplication is to draw a rectangle |dw:1456970481879:dw|

jimthompson5910 (jim_thompson5910):

divide the rectangle into 3 parts. One for each digit of 786 |dw:1456970563201:dw|

jimthompson5910 (jim_thompson5910):

then divide the height into 2 parts (one for each digit of 46) |dw:1456970614087:dw|

jimthompson5910 (jim_thompson5910):

next, we draw diagonal lines that extend out of the original rectangle like so |dw:1456970675131:dw| my drawing is a bit off but it should still work
