$660 ÷ 6 = 110$;
$65 × 30 = 1950$;
$540 × 2 = 1080$;
$10 × 10 = 100$;
$22 ÷ 2 = 11$;
$80 × 30 = 2400$;
$90 × 9 = 810$;
$450 × 3 = 1350$;
$880 ÷ 8 = 110$;
$431 + 253 = 684$;
$129 - 129 = 0$;
$23 × 30 = 690$;
$36 × 40 = 1440$;
$770 - 380 = 390$;
$45 + 56 = 101$;
$560 ÷ 7 = 80$;
$890 - 490 = 400$;
$240 × 5 = 1200$;
$546 + 427 = 973$;
$600 - 230 = 370$;
$360 + 370 = 730$;
$240 ÷ 8 = 30$;
$24 × 40 = 960$;
$50 + 90 = 140$;
$340 - 170 = 170$;
$700 × 3 = 2100$;
$490 + 250 = 740$;
$600 - 268 = 332$;
$340 × 4 = 1360$;
$150 - 121 = 29$;
$360 + 380 = 740$;
$73 × 20 = 1460$;
$390 - 190 = 200$。
60×3÷4
=180÷4=45

24÷8×200
=3×200=600

260+260×9
=260×(1+9)=260×10=2600

23×(24+16)
=23×40=920

168×3×7-168
=168×21-168=168×(21-1)=168×20=3360
答案: 60×3÷4
=180÷4
=45
24÷8×200
=3×200
=600
260+260×9
=260×(1+9)
=260×10
=2600
23×(24+16)
=23×40
=920
168×3×7-168
=168×21-168
=168×(21-1)
=168×20
=3360
