Simply calculate the following questions (1) 4.75 times 10.6 (2) 0.9999 times 0.7 minus 0.1111 times 3.7
Briefly calculate the following questions
(1) 4.75 times 10.6
(2) 0.9999 times 0.7 minus 0.1111 times 3.7
We need to make a formula

4.75×10.6
=（5-1/4）×10.6
=5×10.6-1/4×10.6
=53-2.65
=50.35
The title is wrong
0.9999×0.7+0.1111×3.7
=0.1111×9×0.7+0.1111×3.7
=0.1111×（6.3+3.7）
=0.1111×10
=1.1111
