$8 × 23 = 184$;
$180 ÷ 9 = 20$;
$500 × 6 = 3000$;
$36 ÷ 2 = 18$;
$8 × 50 = 400$;
$800 ÷ 4 = 200$;
$51 ÷ 3 = 17$;
$600 ÷ 6 = 100$;
$700 × 4 = 2800$;
$103 × 3 = 309$;
$500 ÷ 5 = 100$;
$111 - 3 × 6 = 111 - 18 = 93$;
$9 × 17 - 37 = 153 - 37 = 116$;
$25 ÷ 5 × 4 = 5 × 4 = 20$;
$24 ÷ 3 - 2 = 8 - 2 = 6$;
$153 ÷ 9 = 17$;

量出下面各角的度数。


$90^{\circ}$;$60^{\circ}$;$120^{\circ}$;$55^{\circ}$;$75^{\circ}$
答案
本题可根据角的度数测量方法,使用量角器分别量出各角的度数。
用量角器测量角的度数时,把量角器放在角的上面,使量角器的中心和角的顶点重合,$0^{\circ}$刻度线和角的一条边重合,角的另一条边所对的量角器上的刻度,就是这个角的度数。
从左到右各角的度数依次为:$90^{\circ}$;$60^{\circ}$;$120^{\circ}$;$55^{\circ}$;$75^{\circ}$ 。
故答案依次为:$90^{\circ}$;$60^{\circ}$;$120^{\circ}$;$55^{\circ}$;$75^{\circ}$。
