a2b2
Whenever two or more terms (such as a2) are next to each other, multiplication is implied.
The Pythagorean Theorem (the theorem that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides) states that a2 times b2 equals c2.

b times b times b = b3 b plus b plus b = 3b
basically a times b = b times a
b times 7
B added a times would be another way of saying B*a For example if a=4 then B + B+ B + B , which is 4B
ab - eb = b(a - e)
The number of times a divides b is equal to the quotient when b is divided by a.
b2
3 times a times a times b
If a and b are integers, then a times b is an integer.
Both addition and multiplication are commutative and associative operations. Commutative means that the order of the operands does not affect the result (e.g., (a + b = b + a) and (a \times b = b \times a)). Associative means that the grouping of the operands does not change the result (e.g., ((a + b) + c = a + (b + c)) and ((a \times b) \times c = a \times (b \times c))). These properties hold for real numbers and many other number systems.
Yes, it is. sqrt(a+b)=sqrt(b+a) sqrt(a) times sqrt(b) = sqrt(b) times sqrt(a)
