To multiply 82 by 47 using lattice multiplication: Create a 2x2 lattice grid. Write 82 along the top and 47 along the side. Multiply the digits in each box and write the result. Add the diagonals to get the final answer: 82 x 47 = 3844.
I didn't know how much you needed so I went up to 82x82. 82x1=82, 82x2=164, 82x3=246, 82x4=328, 82x5=410, 82x6=492, 82x7=574, 82x8=656, 82x9=738, 82x10=820, 82x11=902, 82x12=984, 82x13=1066, 82x14=1148, 82x15=1230, 82x16=1312, 82x17=1394, 82x18=1476, 82x19=1558, 82x20=1640, 82x21=1722, 82x22=1804, 82x23=1886, 82x24=1968, 82x25=2050, 82x26=2132, 82x27=2214, 82x28=2296, 82x29=2378, 82x30=2460, 82x31=2542, 82x32=2624, 82x33=2706, 82x34=2788, 82x35=2870, 82x36=2952, 82x37=3034, 82x38=3116, 82x39=3198, 82x40=3280, 82x41=3362, 82x42=3444, 82x43=3526, 82x44=3608, 82x45=3690, 82x46=3772, 82x47=3854, 82x48=3936, 82x49=4018, 82x50=4100, 82x51=4182, 82x52=4264, 82x53=4346, 82x54=4428, 82x55=4510, 82x56=4592, 82x57=4674, 82x58=4756, 82x59=4838, 82x60=4920, 82x61=5002, 82x62=5084, 82x63=5166, 82x64=5248, 82x65=5330, 82x66=5412, 82x67=5494, 82x68=5576, 82x69=5658, 82x70=5740, 82x71=5822, 82x72=5904, 82x73=5986, 82x74=6068, 82x75=6150, 82x76=6232, 82x77=6314, 82x78=6396, 82x79=6478, 82x80=6560, 82x81=6642, 82x82=6724
