解:13.8÷[(1.5+2.1)$ imes 4] = 13.8 / (3.6 imes 4) = 13.8 / 14.4 = 1

2. 7.2÷[(3.6-2.8)×0.3]

解:7.2÷[(3.6-2.8)$ imes 0.3] = 7.2 / (0.8 imes 0.3) = 7.2 / 0.24 = 30

3. (345-20)÷(15+20)

解:(345-20)÷(15+20)$ = 325 / (35) = 95 / 7 = 9.3$

4. [200-(74+36)]×15

解:[200-(74+36)]×15$ = (200 - 110) imes 15 = 90 imes 15 = 1350$

5. 8×(12÷4)+7

解:8×(12÷4)+7$ = 8 imes 3 + 7 = 24 + 7 = 31$

6. (24+16)÷(4-2)

解:(24+16)÷(4-2)$ = 40 / 2 = 20 / 1 = 20$

7. (24+16)÷(4-2)

解:(24+16)÷(4-2)$ = 40 / 2 = 20 / 1 = 20$

8. [90-(55+25)]÷5

解:[90-(55+25)]÷5$ = (90 - 80) div 5 = 10 div 5 = 2$

1.(7777+8888)÷5- (888-777)×3

=1111×(7+8)÷5-111×(8-7)×3

=1111×3-111×3

=(1111-111)×3

=1000×3

=3000

2.1111×125+25×7777

=1111×125+25×7×1111

=1111×(125+175)

=1111×300

3.2929×22-8888

=29×101×2×11-8×1111

=(29×2)×(101×11)-8×1111

=58×1111-8×1111

=(58-8)×1111

=50×1111

=55550

4.37×37+2×63×37+63×63

=37×37+63×37+63×37+63×63

=37×(63+37)+63×(37+63)

=37×100+63×100

=3700+6300

=10000
