My students discovered another correct response! 92×76 = 6,992
I can only find the answer 6,992 too
I did 1750 x 4 = 7000!
96
(3*2)+(4*8)
98×71=6958
96×74=7,104 that the close i can get.👍
I got 92×76=6,992
I got 91 times 77= 7007
You can’t use the 7 twice
why can’t she?
The directions said each digit should be used at MOST one time.
My student came up with 92 X 76 = 6992
I came up with 96 x 73 = 7008
89 x 76 = 6764 that’s only 236 away!
I got 6912 (72 x 96)
use the digits 1 to 9, at most one time each, to make 5 prime numbers.
I used 89×76 and got 6,764
89×76=6,764
