Solve the following exercise:

$(+5)\cdot(+5)=$

Due to the fact that we are multiplying two positive numbers together, the result will inevitably be positive:

$+\times+=+$

We obtain the following result:

$+5\times+5=+25=25$

$25$

Solve the following exercise:

$(+6)\cdot(+9)=$

Due to the fact that we are multiplying two positive numbers the result will also be positive:

$+\times+=+$

We obtain the following:

$+6\times+9=+54=54$

$54$

Solve the following exercise:

$(+9)\cdot(+4)=$

Note that we are multiplying two positive numbers, so the result will necessarily be positive:

$+\times+=+$

We get:

$+9\times+4=+36=36$

$36$

$(+7)\times(+1\frac{5}{6})=$

Let's convert the mixed fraction to an improper fraction:

$1\frac{5}{6}=\frac{11}{6}$

Now let's write the exercise:

$7\times\frac{11}{6}=\frac{7}{1}\times\frac{11}{6}=$

We'll multiply numerator by numerator and denominator by denominator:

$\frac{7\times11}{1\times6}=\frac{77}{6}$

Let's convert the improper fraction to a mixed fraction:

$\frac{77}{6}=12\frac{5}{6}$

$12\frac{5}{6}$
