3.8 × 10.1 55 × 9.9 can be simplified

3.8 × 10.1 55 × 9.9 can be simplified

3.8×10.1=3.8×（10+0.1）=3.8+0.38=4.18 55×9.9 =55×(10-0.1)=55-5.5=49.5

Calculate 55 + 5 + 2 + 10 * 05 + 5 =?

72

Calculation: [2 + (5.55 × 4 / 3-27 / 10 △ mouth)] / 0.913 = 10?

10*0.913-2=7.13
5.55*4/3=7.4
7.4-7.13=0.27
27/10=2.7
2.7/0.27=10
Then () is 10

How to calculate 5.4 △ 10.8 + 2 △ 2.5?

Divide first and add later

7 of 18 - (7 of 18-16 of 75) 0.48 × 45.3 + 55.7 × 0.48-48%

7 / 18 - (7 / 18-16 / 75)
=7 / 18-7 / 18 + 16 / 75
=16 out of 75
0.48×45.3+55.7×0.48-48%
=0.48×（45.3+55.7-1）
=0.48×100
=48

8.4-8.4 * 0.75 = how to calculate

8.4-8.4*0.75
=8.4x(1-0.75)
=8.4x0.25
=2.1x4x0.25
=2.1x1
=2.1
