一、我会计算。
$11 - 6 = $
$14 - 6 = $
$11 - 8 = $
$11 - 6 = $
5
$16 - 8 = $8
$13 - 7 = $6
$4 + 7 - 5 = $6
$14 - 6 = $
8
$10 - 3 = $7
$13 - 9 = $4
$18 - 8 + 4 = $14
$11 - 8 = $
3
$12 - 8 = $4
$12 - 3 = $9
$10 - 4 + 7 = $13
答案:
5 8 6 6 8 7
4 14 3 4 9 13
4 14 3 4 9 13
二、在$◯$里填上“$>$”“$<$”或“$=$”。
$90◯$
$78 - 8◯$
$90◯$
=
$93 - 3$ $79◯$<
$85 - 5$ $100◯$>
$90 + 9$$78 - 8◯$
<
$80$ $7 + 40◯$<
$49$ $20 + 6◯$<
$30$
答案:
= < > < <
<
<
