Because that's how the addition and multiplication functions were defined.
A number with more than 2 digits must be at least 100. Any two numbers of this kind will give an answer that is at least 10000. So there are no ways to make 144 with multiplication of numbers with more than 2 digits.
Multiplication by an integer is the same as repeated addition.
The number 18 can be expressed in various ways depending on the context, such as through addition, multiplication, or using combinations of numbers. For example, in addition, it can be made by summing pairs like 9 + 9, 10 + 8, or 15 + 3. In terms of multiplication, it can be formed by products such as 2 × 9 or 6 × 3. The total number of ways to make the number 18 varies based on the specific mathematical operations or constraints applied.
Simple and Traditional multiplication. Then there is Long Multiplication. used for larger numbers. e.g. Simple multiplication 3 x 2 = 6 Long Multiplication. 33 x 22 = 33 x 22 660 66 726 ====
There are many ways to make the number 50 by combining different numbers through addition, subtraction, multiplication, and division. Some examples include 25+25, 100-50, 10*5, and 100/2. The total number of ways to make 50 depends on the range of numbers and operations allowed in the calculation.

You are working with numbers. One is a whole number and the other is a fraction of a whole number (with a decimal point, etc). You apply the same principles of subtracting one number from another or a fraction of one number from a fraction of another. Numbers is numbers!
With whole numbers, there are five ways.

Multiply:1x15=1515x1=153x5=155*3=15*With multiplying fractions, there are an infinite number of ways to get the product of 15, but the four listed above are used by multiplying whole numbers.
There are infinitely many ways. Think of any number, say x. calculate y = 13 - x Then x + y = 13 Since the choice of x was arbitrary, there are infinitely many answers. That applies to pairs of numbers. You can repeat the process for sums of 3, 4, ... numbers. Also, you can look at multiplication and other ways of combining numbers (binary operations).
