Fill in the appropriate operation symbol in o to make both sides of the equal sign equal 1、3 3 3 3=1 2、3 3 3 3=2 3、3 3 3 3=3

Fill in the appropriate operation symbol in o to make both sides of the equal sign equal 1、3 3 3 3=1 2、3 3 3 3=2 3、3 3 3 3=3

(3*3)/(3*3)=1
(3/3)+(3/3)=2
3*3-3-3=3

Fill in the appropriate operation symbol in 0 to make both sides of the equal sign equal
6 0 3 0 4 0 2 is equal to 1
6030402 is equal to 20
6 03 04 02 equals 24
6 03 04 02 equals 11
6 0 3 0 4 0 2 equals 4
6 0 3 0 4 0 2 is equal to 10
Note: (parentheses can be used)

6 / 3 / 4 × 2 equals 1
6 × 3 + 4-2 equals 20
6 × 3 + 4 + 2 equals 24
(6 × 3 + 4) △ 2 equals 11
6 / 3 + 4 / 2 equals 4
6 × 3-4 × 2 equals 10

How to calculate the recursive equation skillfully in primary school mathematics
425-132+268

If there is a problem, you can't calculate it skillfully

5.6×69.32＋138.64×0.05＋693.2×0.43
-------------------
Remember!

5.6×69.32＋138.64×0.05＋693.2×0.43
=5.6×69.32+69.32*2*0.05+693.2*0.1*10*0.43
=5.6×69.32+69.32*0.1+69.32*4.3
=69.32*(5.6+0.1+4.3)
=69.32*10
=693.2
