evaluate- 2.4+4-3(1-2)?

Reading this as :-
2.4 + 4 + 3

2.4 + 4-3(1-2)
----

6.4 + 4 -3(-1)
6.4 + 4 + 3
9.4

2.4+4-3(1-2)
2.4+4-3(-1)
2.4+4+3
4.4+3
=9.4

Always follow the order of operations. PEMDAS is a good way to remember what to do first. Parenthises, Exponents, (going from left to right) Multiplication, Division, (going from left to right) Addition, Subtraction.

(2x4) + (4-3)(1-2)
= 8 + (1)(-1)
= 8 - 1
= 7

2.4 + 4 = 6.4
(1-2) = -1
-3(-1) = +3

6.4+3 = 9.4

That is it, baby step by baby step.

PEMDAS

2.4 + 4 + 3
6.4 + 3
9.4

6.4-3(-1)= 6.4+3=9.4

2.4 + 4 - 3(1 - 2)
= 6.4 - 3 + 6
= 3.4 + 6
= 9.4

2.4+4-3(1-2)
= 2.4+4-3(-1)
=2.4+4+3
=9.4

Other solution
2.4+4-3(1-2)
=2.4+4-3+6
9.4
Hope this helped!

2.4+4-3(1-2)
2.4+4-3(-1)
2.4+4+3
=9.4

Please note: You must always follow the rule of BEDMAS. So according to your question, brackets first...then multiply...an solve right through (addition/subtraction)
