Two numbers are multiplicative inverses when their product results in .
For example:
and are multiplicative inverses because
Two numbers are multiplicative inverses when their product results in .
For example:
and are multiplicative inverses because
Whenever a is different from , it follows that
Division is equivalent to multiplication by its multiplicative inverse,
That is:
Because is the multiplicative inverse of
Generally:
\( 8\times(5\times1)= \)
\( 7\times1+\frac{1}{2}= \)
\( \frac{6}{3}\times1= \)
Solve the following exercise:
\( 12+3\cdot0= \)
Solve the following exercise:
\( 2+0:3= \)
According to the order of operations, we first solve the expression in parentheses:
Now we multiply:
40
According to the order of operations rules, we first insert the multiplication exercise into parentheses:
Let's solve the exercise inside the parentheses:
And now we get the exercise:
According to the order of operations rules, we will solve the exercise from left to right, since there are only multiplication and division operations:
Solve the following exercise:
According to the order of operations, we first multiply and then add:
Solve the following exercise:
According to the order of operations rules, we first divide and then add:
\( \frac{25+25}{10}= \)
\( 0:7+1= \)
\( 12+1+0= \)
\( 0+0.2+0.6= \)
\( \frac{1}{2}+0+\frac{1}{2}= \)
Let's begin by multiplying the numerator:
We obtain the following fraction:
Finally let's reduce the numerator and denominator by 10 and we are left with the following result:
According to the order of operations rules, we first divide and then add:
According to the order of operations rules, since the exercise only involves addition operations, we will solve the problem from left to right:
13
According to the order of operations rules, since the exercise only involves addition operations, we will solve the problem from left to right:
0.8
According to the order of operations, since the exercise only involves addition operations, we will solve the problem from left to right:
\( 9-0+0.5= \)
\( 19+1-0= \)
\( 2+0:3= \)
\( 12+3\times0= \)
\( 1\times\frac{1}{2}:2 \)
According to the order of operations rules, since the exercise only involves addition and subtraction, we will solve the problem from left to right:
9.5
