1, conversion of single unit

Big and small, long tail, just add a 0; Small to big, tail off, remove 0 to grow up!

For example, 7 yuan = () angle, from yuan to angle, large units become small units, that is, "long tail", and just add a 0 after 7. 30 points = () angle, from small units to large units, just remove the tail 0!

2. Divide two units into one unit and one unit into two units.

Just add an adjacent unit bigger than yourself in the middle of two digits of a unit, or remove the big unit in the middle of two units.

For example: 1 yuan 3 angle = () angle, two units become one unit, and the conversion is realized by removing the large unit "yuan" in the two units. 28 points = () angle () points, one unit becomes two units, so split the two digits into large units and put them in small units. Or just fill in the adjacent large unit "angle" between 2 and 8.

3. RMB conversion formula

Canadian dollar, RMB minus RMB.

Angle plus angle, angle minus angle; Earning a dollar and earning a dime is not enough to borrow a dollar and a dime.

Points plus points, points minus points; Ten cents becomes ten cents, not ten cents becomes ten cents.

4, RMB conversion jingle

Big and small, long tail, just add a 0;
