You have mentioned '7' three times in the question.
This is a tip-off that you could multiply 7 "times" 3 and get 21.
7 times 3
7*3= 21
No, it is not.
1 x 7 plus 2 x 7 is the same as 3 x 7
Order of operations: The final multiplication has priority - do it first, then add.You can simplify the problem. 11*7= 77.
Just do 7 x 3. Because it's 7 three times.
Multiplication and addition.
If you just switch the numbers around (in either multiplication or addition) it is the commutative property.
7x4=28
The sum of 7 plus 7 is fourteen (14). This level of math is usually learned by elementary school students who memorize basic arithmetic such as addition and multiplication.
7×7× 7×7×7×7×7
Following order of operations, multiplication happens first. Addition happens second. 7+6*42*2 =7+504 =511
