reminder first: do not forget to align the point on decimal.
1. first step:
multiply the number from left to right
8.32 4x2=8
x4.64 4x3=2 why? Because you need to place the 1 at the top of 8
then add it, before that 4x8 is 32 then add 1 equals 33
it's time for second place (6).. ok.. 6x2=12, place number 1 at the top of number 3 and 6x3=18 + 1= 19, place number 1 from 19 to the top of 8 and multiply 6 and 8 so 48+1= 49 then the third place (4), 4x2=8, 4x3=12, place 1 at the top of the 8 and 4x8=32+1=33 so, the answer we got is.3328, 4992, 3328 add them at this position:
3328 why did I put the decimal point after the number 38?
4992 look at the problem 8.32(there are two numbers after
+3328 the decimal point) 4.64 same as I tell you about 8.32
