Addition, Subtraction, Multiplication and Division: Only addition and subtraction

According to the order of operations, solve the exercise from left to right since the only operations in it are addition and subtraction:

$10-3=7$

$7+7=14$

$14-5=9$

According to the rules of the order of arithmetic operations, we solve the exercise from left to right since it only has addition and subtraction operations:

$-7+5=-2$

$-2+2=0$

$0+1=1$

According to the rules of the order of arithmetic operations, we will work to solve the exercise from left to right:

9+3=11

11-1=10

And this is the solution!

According to the rules of the order of operations, given that the exercise only involves subtraction and addition operations, we solve the exercise from left to right:

$3+2=5$

$5-1=4$

According to the rules of the order of operations, we will solve the exercise from left to right since it only has addition and subtraction operations:

$9-3=6$

$6+4=10$

$10-2=8$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$12+6=18$

$18-4=14$

$14+18=32$

$32-12=20$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$14-5=9$

$9-9=0$

$0+7=7$

$7+2=9$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$21-3=18$

$18-6=12$

$12+9=21$

$21-5=16$

Due to the fact that the exercise only involves addition and subtraction operations, we will solve it from left to right:

$26-6=20$

$20+9=29$

$29+7=36$

$36-12=24$

Insofar as the exercise only involves addition and subtraction operations, we will solve it from left to right:

$30+6=36$

$36-5=31$

$31+7=38$

$38-17=21$

$100+5-100+5=105-100+5=5+5=10$

According to the rules of the order of arithmetic operations, we solve the exercise from left to right since it only has addition and subtraction operations:

$3+4=7$

$7-1=6$

$6+40=46$

Let's begin by expanding the parentheses. Make sure to pay attention to the minus and plus signs, which change accordingly:

$-(-5)=5$

$8.5+(-13)=8.5-13$

We should obtain the following:

$-7+5+8.5-13=$

Now let's solve the exercise from left to right:

$-2+8.5-13=$

$6.5-13=-6.5$

Let's begin by expanding the parentheses whilst paying attention to the minus and plus signs, which change accordingly:

$+(-9.5)=-9.5$

$+(-13)=-13$

We should obtain the following:

$7.5-9.5+5-13.5=$

Now let's solve the exercise from left to right:

$-2+5-13.5=$

$3-13.5=-10.5$

First, we solve the exercise:

$4+7-3+1-5 =$

According to the rules of the order of operations, we solve the exercise from left to right:

$4+7=11$

$11-3=8$

$8+1=9$

$9-5=4$

Now we solve the exercise:

$4+(7-3+1-5) =$

According to the rules of the order of operations, we first solve the parentheses and then we will join:

$(7-3+1-5)=$

$(4+1-5)=$

$(5-5)=0$

$4+0=4$

Therefore:

$4=4$
