50
but how
In order to solve the expression, you need to follow the order of operations, which is often remembered using the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
First, you need to simplify the expression inside the parentheses: 1 + 9 equals 10.
Next, multiply 5 by the result of 10: 5 × 10 equals 50.
Therefore, 5⋅(1+9) equals 50.
5⋅1+5⋅9 equals
plus+
which equals
.
To solve the expression 5⋅1+5⋅9, you need to follow the order of operations. First, perform the multiplications:
5⋅1 = 5
5⋅9 = 45
Next, perform the additions:
5 + 45 = 50
Therefore, 5⋅1+5⋅9 equals 50.
8⋅(7−1) equals 8, dot8⋅
which equals
.
To solve the expression 8⋅(7−1), you need to follow the order of operations. First, perform the subtraction inside the parentheses:
7 - 1 = 6
Next, multiply 8 by the result of 6:
8⋅6 = 48
Therefore, 8⋅(7−1) equals 48.
8⋅7−8⋅1 equals
minus−
which equals
.
To solve the expression 8⋅7−8⋅1, you need to follow the order of operations. First, perform the multiplications:
8⋅7 = 56
8⋅1 = 8
Next, perform the subtraction:
56 - 8 = 48
Therefore, 8⋅7−8⋅1 equals 48.
5⋅(4−3) equals 5, dot5⋅
which equals
