$1+6=7$

And we get:

$1.02\\+6.40\\7.42$

To avoid confusion in solving the exercise, we will first add the digit 0 to the number 112.3 as follows:

$111.25\\+112.30\\$

Now let's solve the exercise in order:

We'll combine the hundredths after the decimal point:

$5+0=5$

We'll combine the tenths after the decimal point:

$2+3=5$

Finally, we'll combine the whole numbers before the decimal point accordingly:

$1+2=3$

$1+1=2$

$1+1=2$

And we get:

$111.25\\+112.30\\223.55$

Let's solve the exercise in order:

We'll add up the thousandths after the decimal point:

$2+3=5$

We'll add up the hundredths after the decimal point:

$1+1=2$

We'll add up the tenths after the decimal point:

$5+3=8$

Finally, we'll subtract the whole numbers before the decimal point:

$3+4=7$

And we get:

$3.512\\+4.313\\7.825$

Let's solve the exercise in order:

We'll add up the hundredths after the decimal point:

$8+1=9$

We'll add up the tenths after the decimal point:

$3+4=7$

Finally, we'll add up the whole numbers before the decimal point accordingly:

$1+3=4$

$2+1=3$

And we get:

$21.38\\+13.41\\34.79$

Let's solve the exercise in order:

We'll subtract the hundredths after the decimal point:

$9-3=6$

We'll subtract the tenths after the decimal point:

$2-1=1$

Finally, we'll subtract the whole numbers before the decimal point accordingly:

$3-2=1$

$1-1=0$

And we'll get:

$13.29\\-12.13\\01.16$

Let's solve the exercise in order:

We'll subtract the tenths after the decimal point:

$1-0=1$

Finally, we'll subtract the whole numbers before the decimal point accordingly:

$2-2=0$

$2-1=1$

And we get:

$22.1\\-12.0\\10.1$

Let's solve the exercise in order:

We'll subtract the hundreds after the decimal point:

$0-0=0$

We'll subtract the tenths after the decimal point:

$1-1=0$

Finally, we'll subtract the whole numbers before the decimal point accordingly:

$3-1=2$

$3-1=2$

And we get:

$33.10\\-11.10\\22.00$

Since there are only zeros after the decimal point, we can ignore them and we actually got the number: 22

To avoid confusion in solving the exercise, we will first add the digit 0 to the number 30.1 as follows:

$33.23\\-30.10\\$

Now let's solve the exercise in order:

We'll subtract the hundredths after the decimal point:

$3-0=3$

We'll subtract the tenths after the decimal point:

$2-1=1$

Finally, we'll subtract the whole numbers before the decimal point accordingly:

$3-0=3$

$3-3=0$

And we get:

$33.23\\-30.10\\03.13$

We will break down each of the factors in the exercise into a whole number and its remainder.

We get:

$8+0.5+5+0.2+8+0.4=$

Now we'll combine only the whole numbers:

$8+5+8=13+8=21$

Now we'll calculate the remainder:

$0.5+0.2+0.4=0.7+0.4=1.1$

And now we'll get the exercise:

$21+1.1=22.1$

According to the order of operations, we will solve the exercise from left to right.

We will first calculate the addition exercise in the vertical column, since it contains two numbers after the decimal point:

$0.85+7.61=8.46$

Now we will get the exercise:

$8.46+2.3=$

Let's remember that:

$2.3=2.30$

We will calculate in the vertical column and get:

$10.76$
