1. 直接写出得数。
64 - 16 = 109×4 = 139 - 57 = 37 + 58 - 16 =
920 - 370 = 190÷2 = 48 + 98 = 83 - 25 - 37 =
58 + 23 = 872÷4 = 117÷3 = 400÷5×0 =
93÷3 = 420÷3 = 45×8 = 540÷9÷6 =
160÷2 = 21×9 = 730 - 280 = 32×4 + 7 =
515÷5 = 6×34 = 91 - 22 = 180÷(78 - 69) =
4×65 = 510×8 = 416÷8 = 16 + 84×5 =
29×6 = 803×2 = 602÷2 = 7×(336 + 64) =
64 - 16 = 109×4 = 139 - 57 = 37 + 58 - 16 =
920 - 370 = 190÷2 = 48 + 98 = 83 - 25 - 37 =
